While each line has it's pro's and con's, I think that the Buffy line is the best in terms of sculpts and depth. I think only the Willow figure is sub-par in temrs of sculpt, and the diversity of the line is pretty great (although a few too many Spikes/Angels, while others are still missing). That being said I haven't seen the Planet of the Apes up close, but the reviews that Michael Crawford does sure makes them look amazingly well done.
