The 333xl is the better of the 2 amps generally speaking, but it's also a bit more expensive, If you have the cash go for the 333, it will do everything the 6262 can do and more.

I have a bugera 1990, had it for a year and no problems, great sound too, i love it.

The best thing you can do is try to go to a store where you can try one out.
