I have almost completed my first AVR project using a Mega 128 and WINAVR/GCC.  Initialy I disliked it because it's optimisation is poor in a few areas, especialy compared to HiTech's offerings which I have been using for years. e.g. a trival (and common) operation such as setting a bit within a multi-word variable takes something like 12-15 instructions rather than the 1 or 2 it should take.

However, the raw speed of the AVR means that my usual paranoia over wasted cycles was not really justified.  Compared to the PIC I was able to write some very clean, well abstracted code and still have plenty of cycles in hand.  Also, it's optimisation is generaly very good.

So far I've not come across any actual bugs in the compiled code which is a pleasant change.  The AVR Freaks forum provides pretty good support.  The latest version AVR Studio also supports GCC properly, so you can use it as a full blown IDE, though it's simulator and debugger still seem to have the occaisional problem with the .elf files generated by WINAVR (and it takes an eon to load a big elf file, a minute or so on my lowly P3 work machine.)
