PICs do have a lot of support out there and there thousands to choose from.
But they're not as quick as an AVR (dont flame me please)

Dont know about lawsuits but...
MPASM and the AVRASM languages are different, many different commands,
but they are similar enough that you can get tools to convert from MPASM to
AVRASM,
though Ive not seen to go the other way ;-)
The problem with assembler programming is that each time you pick up a new
processor
you have to learn the instruction set again.
The AVR was design to host C (it has 32 registers and you can use 6 to give
you 3  16Bit pairs)
C is nice as its almost cross platform learn it and most of you programs
will go straight from one
processor into another. But its not as effecient as asembley programming
(space/speed).
Ive done a little with C, and what Ive found is its great to get complex
stuff done but when I need
the speed I go into the asembler file it generates and tinker with it to
make it faster.
