I think if you "study" either one of them and therefore think it is too much bother to study the other some time in the future, that you haven't learned anything at all.

On email lists and forums we see this all the time with AVR users not even willing to consider a PIC or ARM. And vice versa. Is often so bad that 8535 users won't consider AT-Mega parts, never mind the less-than 10,000 quantity price of the the older 8535 is essentially the same as for more capable parts.

I seriously recommend that you revisit your CPU selection looking for an AVR with JTAG or Debug-wire interfaces for on-chip symbolic debugging. Strongly suggest that you study the AVR Dragon and specifically the CPUs that the Dragon supports. The Dragon costs roughly $50. The next step up is $300 and isn't really any better for CPUs that the Dragon supports.
