Relevant tale time - I wanted a SCAR-L. I read ABSOLUTELY everything I could find about all the different versions (VFC, G&G, TM Recoil) and I agonised over whether or not the extra cost of the TM was worth the recoil/bolt stop etc or if the VFC really was the most accurate externally. Then I got bought the G&G as a present and I bloody love it. Would I have loved the others more? Maybe - who knows? I know I don't give a crap any more because I have a gun I love that works and shoots straight and when it all boils down to it, that is pretty much all I care about.
Stop worrying, pick one and play. Life's too short.
