What do people think of each of these...?
CodeVision C for AVR
ImageCraft C for AVR
IAR C for AVR
gcc for AVR
BASCOM for AVR
Any of them notoriously good or notoriously bad?
Integration with AVR Studio and STK500 are desirable.

I'm really interested in developing my application on AVR MCUs using

If anyone can tell me when to use AVR and when to 8051.
We all have known that AVR has fine instruction set and

During product developing, what make you choose 8051?
Any comment is appreciated.

The following link (http://tomscarff.tripod.com/cv2midi/cv2midi.htm) shows a

Is there any AVR compiler with MIDI functions?
