how different is pic assembler and avr assembler?

Consider the pic the root RISC microcontroller and the avr one branch of it. Read the application notes to the 16c54 or the 12c508, if you understand those (I'm 99% sure you'll understand it), then you understand and can program pretty well all pic chips. All others have more stuff.

The assembler is the easy bit. You'll be spending much more time figuring out the different processor architectures. If you learn AVR first you'll be annoyed with the way the PIC does things such as pages for status registers and the concept of the "working" register.

..... and after you've figured out PICs, you'll go back to AVRs because you'll still be annoyed with the way the PIC does things such as page/bank switching and the concept of the (singlular) "working" register. ;-)
