You should always do research into whatever gun you buy there are a lot of reviews out there to see. look for the ones done by actual owners of the gun who have had it a while rather than the ones done by a 10yr old or the people trying to sell it to you. Also consider availability of replacement parts, upgrades, accessories and mags. It may not be unique to have the most common gun but it can have it's advantages.
Edit: I use an Ics Sig 551 and a KSC Glock 17 they're both great as far as I'm concerned.
