Which storm mesa gives out the best chest I can only go in 1,2 and 3
Typically you want to do the highest Mesa you can.
However, if I'm not mistaken, Storm Mesa 2 can give the "Hero Altar Expansion Card", which is kinda nice to get for free.
That aside though, it doesn't take all that much these days to do Mesa 4 (and there are a whole lot more people doing it so it's easier to get groups). I wouldn't worry about 1, 2, and 3 all that much.
