Something comparable and compatible with tetrix

I am currently using Tetrix Max in my robotics academy. I am not too pleased with the quality. I wanted to know what I can use that is comparable, compatible and better quality with tetrix.
The motors are waaaaay too slow (even geared up) so I would def. want to upgrade them. Do you guys have anything in mind?

Even if I have to order new kits I would love the suggestions. I would like more than 4ch., the ability to add a bunch of motors and servos, durable

If you guys have ideas on projects to build with the kids that would be awesome!

Thanks guys!
