I emulate both. I love both. (Obviously not enough to actually buy the systems though xD)

For me SNES vs. GBA equates to Chrono Trigger vs. Golden Sun 1/2.

It's really tough to green light one as the better one because both games are just so much better than any other console RPG I've played.

In the end I'll go with CT, which means I love SNES more.
