Always been a fan of manuals.
as far as skaters who have done tasteful manuals, daewon, bobby dekeyzer, preston harper, biebel come to mind,
Random favorite manual: Last trick in this part
also kenny hoyle's switch manny switch heel out 3up-3down in his kayo part.
If you're balancing for more than 3-4 seconds before flipping out or exiting the wheelie, manuals can be super boring though.
