68000 and 68020, then Atmel AVR. Recently DSPIC

I've never liked PICs. They're slow,
expensive and very hard to develop for,
thanks to the sheer lack of support -
and last time I looked you had to pay
extra for surface-mount!<br>
<br>
I used AVR for a bit but I'm moving over
to STM32 - ridiculously cheap and
ridiculously fast.<br>
<br>
This must be a personal taste thing, as
I have no problems at all programming
with PICs. The documentation is very
good, and there are lots of examples to
get over the most difficult part which
is how to set the various switches (in
AVR world the equivalent is the
"fuses"). I've actually had more
frustration figuring out how to set
fuses, to be honest. I haven't played
with the STM32s, I'll certainly have to
give that a try.<br>
