I used to find that the Ibanez RG and JEM shapes seemed to fit me best. Had many of them over the years. Sat nice on the body when both standing and sitting. I never found a typical Fender Strat type that felt that good to me. This was until I picked up my first Washburn N4, Nuno's sig guitar.

They have cut down Strat bodies which I thought was going to be a problem for me being 6ft tall and medium build, but the body size fit's like a glove. The swampash ESA model is very very light without being neck heavy and both the Alder and Padauk's (very heavey - custom only) are very well balanced when standing.
Other than having a smaller body, the most ergonomic thing I have found is the Steven's extended cut away, which add's to the overall shape and detailing. Helps make the whole thing lighter also I guess, but for me the cutdown body is amazing.
