I used both, 16Fxxx PIC series and ATMEL ATMEGA series.

PIC require assembly programming for best performance and require also an=
=20
hardware programmer.

ATMEL can be programmed in standard C/C++ language; AVR C compiler is GNU=
 open=20
source for Windows, Linux and MAC OS, and provide long integer and also=20
floating point. You can also generate intermediate assembly source from C=
 and=20
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 connecti=
on=20
with PC. Edit program, compile, upload and test. Many clones with some lit=
tle=20
differences.

In my opinion the hardware is good, the development environment not so goo=
d=20
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 ME=
GA=20
xxx it's impossible without external HW, so... I use both but I prefer=20
ATMEL ;-)
