I've been really enjoying Intel One Mono which seems to solve this by adding more space around most characters (two extra pixels per side at the size I like, about 17px capital letter top to bottom if I counted right) except the m and w (I think, I didn't check everything; they still get one pixel on each side). It also has a low x-height and tall line height and doesn't even try to work at small font sizes but it looks really nice if you make it big enough. Comparing with my previous favorite DejaVu Sans Mono (aka Bitstream Vera Sans Mono) it seems like all the extra space visually evens out the letters and it works well without this kind of adjustment.
