Try ARM. x86 assembly is ugly and wart ridden. ARM is like a breath of fresh air. Unbelievably well designed.

Although I wouldn't recommend choosing assembler for a destkop app, but it made sense when they were written. And I still think Impression beats many a word processor and DTP package available today, and it ran in 2MB of memory with no hard disc.
15 years ago, I did Intel-style assembly--and loved it even with all its clumsiness. But I just dove into ARM a few weeks ago, and am loving it even more. Such sweet pleasure to code so close to such a beautiful and simple machine!
