I used both, 16Fxxx PIC series and ATMEL ATMEGA series.
PIC require assembly programming for best performance and require also an
hardware programmer.
ATMEL can be programmed in standard C/C++ language; AVR C compiler is GNU open
source for Windows, Linux and MAC OS, and provide long integer and also
floating point. You can also generate intermediate assembly source from C and
C++ source and you can write interrupt driven functions in C.
See this URL http://www.arduino.cc
many cheap development board, open source hardware, need only USB connection
with PC. Edit program, compile, upload and test. Many clones with some little
differences.
In my opinion the hardware is good, the development environment not so good
but it's open source and all library sources are useful.
Last: with PIC 16Fxxx is easy to make a 40 MHz frequency meter, with AT MEGA
xxx it's impossible without external HW, so... I use both but I prefer
ATMEL ;-)
