Isn't it fine when you drop \compose and replace it by \circ? 

I even would not be willing to type `\comp{f}{g}' in place of `$f \circ g$' or, in equations, `f \circ g'. Or \let\comp\circ to see "what you mean" rather than "what you get". 

I guess not the vertical placement is bad, it is choosing \scriptstyle that chooses a font size too small between normal size symbols.
