I have yet to see a scenario in FRC where a stronger alloy than 6061 was needed for frame members.

The only application where it makes sense is shafts, gears, and sprockets.

5052-H32 or 34 is the default material for anything that gets bent. Look at any successful sheet metal drive from recent years and it's not going to use anything fancier. It's all about how you design and load the members, not the alloy type.
