Perhaps the following would be a bit of good advise. Join a local club, chat to the blokes you will be flying with and who ultimately will be helping you. See what mode they are flying. As it helps very little if everyone is on mode 2 and you are on mode 1 and you need some help. And at some stage everybody needs some help in this hobby be it just an engine not running correctly or sticking servo or a glitch that you just cannot track down. I found that especially when starting out a lot of help was given to me by club members even today it is always best to discuss your new purchase, it's amazing what mods they will come up with to improve flight performance etc.

Anyway just my 2 cents worth. All the best with your decision.

By the way I fly mode 1 but I am in Aussie if I was in the States I would probably fly mode 2!
