I'm honestly ok with prefixing registers with a consistent symbol, and discerning for eg. immediates and literal addresses in a uniform way is pretty useful in a lot of instruction sets. I think those are ok. On the other hand, though, there are the ways that it diverges semantically from the platform's norm: Indexed-mode, like you said, adding suffixes (for word size) to opcodes, the always popular reversal of src,dst arguments. That's where it bothers me. When you put it all together though it just gets a lot more frustrating. On the plus side at least you always know what you're looking at.
