My two G36s are just as reliable and trouble-free as my two G30s, my G21 and my two G19s.
They're certainly the easiest Glocks to use for CCW that I own.
The G36s are also easy to shoot well, like most Glocks.
The only Glocks I've had that gave trouble were both .40s (one each G23 and G27), and I got rid of 'em. Won't have a .40S&W gun anymore.
