> I don't like all of them
I hate all of them with a passion, because they look like a glyph (i.e. "something you can erase with a single backspace") but aren't. This confuses me first, and annoys me second. "Just because we could" doesn't mean that we should.
Imagine having to use Backspace twice to erase e.g. Ö or Ñ, or being able to place your cursor halfway inside Æ.
Amen. Very well put.
