Since I own both, I'm going to have to say that the F4 is actually a bit nicer, due to the features listed above. Luckily, F3's are cheap, so you can pick up one along with an F4s and only spend about $300 or so. The main reason why I still have my F3, is due to it being the P version with the hot shoe on the prism. At least, it lets my SB-25 do non-TTL automatic without an adapter...
