I like C because I can write code that works the same on AVR, ARM, PC,
whatever. I still dabble in assembler when its needed, but I work with
too many different processors to keep all of the different assembly
languages straight in my head. Maybe this is just a sign of old age...

I've been using C for over 20 years, and I've probably used it on over
a dozen different architectures. I've probably handcoded assembly code
for all of those platforms too.

For people who are willing to put in the effort, you can get tighter
faster code by developing everything in assembler. Although on some
architectures the compiler will often do a much better job, unless
you're really really good at the assembler stuff. This is especially
true with the more advanced processors which have big pipelines, and
parallel execution units, etc.

Personally, I don't think C is better than assembler, nor do I think
that assembler is better than C. They're different. They have
different advantages and disadvantages. You have to make the trade
offs and decide which one is best for you and your particular
application.
