There are only two reasons NOT to get the automatic. One is that it has less horsepower. Two is that it isn't appropriate in stock form for performance modifications. (Some might say that a third reason is that the "automatic is not cool", but I don't think that is a reason, it is an opinion.) There are offsetting reasons TO get an automatic. One is that a lot of clutching and shifting while creeping through traffic regularly is hard on the clutch (which is a wear item) as well as just plain annoying. Okay, traffic is finally moving, ease up on the clutch, accelerate, clutch and shift, we are moving now, and...brake lights! Back on the clutch and downshift, okay, here we go again, clutch and shift accelerate and clutch and shift and....brake lights again! Repeat 500 times until you finally break out of traffic.. The second is that frequently the women in your life can't drive a stick, so the automatic is a good choice for them. A third reason is that when I am doing triple digit speeds I prefer to focus on driving the car instead of managing the transmission.
Personally, a manual transmission car seems like an anachronism to me, and a manual transmission car with manual steering (early cars) particularly seems like an anachronism to me. (Why not run bias-ply tires and a three on the tree?) But that is just my opinion.
The automatic is a great car, great in traffic, and is a real pleasure to drive, plus the wife, girlfriend, or daughter can drive it. On the few occasions when I am driving at triple digits I prefer having my focus on driving the car, not managing the transmission. There is nothing wrong with an automatic whatsoever, it just isn't quite as performance oriented as the manual. It is more of a "gentleman's NSX". It was detuned by honda to take the pressure off the automatic transmission. The automatic transmission is great in traffic and for high-speed driving and is up to the task for it's purpose, but if you are going to drive your car harder than normal and maybe intend to do performance upgrades or indulge in track time you should stick with the manual. If you intend to leave the car stock and enjoy it the way it is then the automatic is a great choice. You should decide based on how you intend to use the car and what your priorities are.
Frankly, most people seem more concerned with this issue based on what they think other people will think or say, rather than what their own needs are. You should evaluate based on your personal needs and preference, not what someone else thinks is "cool". I personally am willing to give up the extra horsepower for the pleasures of the automatic, but for you, the answer may be different. Ask yourself, am I only concerned about the automatic because of what I think other people might say? Or do you really want every extra horsepower you can get. If you don't think the horsepower is that big of a deal, because both cars are still plenty fast, you might be happy with the automatic. But if not having the extra horsepower would still bug you, you should get the stick. If it would still bother you that someone online (this doesn't happen in real life) will say that your car is not "cool" because it is an automatic, then you should get a stick. If it would still bother you that online (this doesn't happen in real life) someone will say it isn't a "real sports car", then you should get a stick. If you want to drive the car really hard and take it to the track, you should get a stick. If you want to add a supercharger or otherwise boost performance, then you should get a stick. If, on the other hand, you really don't mind what people say so much and you would like to have a great car without all that shifting, plus one that the woman in your life can drive, then go ahead and get an automatic. The automatic is a great car, I highly recommend it. Just be aware that you will have to defend the car (online) against people who say it isn't a "real sports car". If you get an automatic, don't get your feelings hurt when somebody says it has "only 252hp". Don't try and turn it into something else with the speed mods, etc, just so you can say that you have as much hp as the next guy. Buy the automatic, drive it, enjoy it for what it is, and be happy with it. The only thing "wrong" with the automatic is all the negative comments you will hear about it from people online. The car itself is fine. I have a lot of traffic to wade through and I am very happy with the automatic. No one has ever approached me in real life and told me what a loser I am for having an automatic.
You might enjoy the automatic for the qualities it offers, or you still might decide that the manual is the right car for you. The automatic is a fine car and there is nothing inherently "wrong" with it. Bottom line, figure out what your own personal priorities are and go with that. Both the automatic and stick cars are great, they just offer slightly different trade-offs.
I once loaned my car to a friend who usually drove a manual transmission BMW. He is one of those who is of the opinion that a stick is "better". He took the car on a 2000-mile trip, and when he got back he announced that to his surprise he really enjoyed the automatic because it allowed him to focus on driving the car instead of managing the transmission. Having said that, in only a few weeks he was back to being interested in finding a manual transmission NSX, because in his mind the automatic still wasn't cool, and he seemed to care more what someone else might think than what his own personal experience was. Even his own experience wasn't enough to make him give up the "stick is better" mentality.
After having written all of the above, I have come to believe that since you hesitated when it you had the opportunity to buy an automatic, you must be like my friend (nothing wrong with that), and should just buy the stick. Having the automatic would bug you too much.
