This one is pretty good, but it has one common flaw that other implementations have: lots of empty space between controls.

Win95/98 was very efficient in this area. Too much empty space wastes the space.

Totally agree and I think the root cause are today's larger screen sizes, less constraints. Win95 was designed at a time when 800x600 and 1024x768 have been the standards to work with.
