If you are going to try PES, mod it either with PES Smoke Patch or PESEdit patch
Its not just the graphics, licences etc that are changed... but also gameplay, ball physics, referees, pace of the game, remove the catchup logic of defenders being able to hang tough in a foot race with say Bale... lots of stuff. Have a read... as I say its not perfect but you might find something in there that you enjoy.
FIFA 14 also has mods, but being honest ive not tried them... but given the size of the community, i wouldnt be surprised if they did similar to FIFA as to what mods do for PES. So again before giving up on FIFA, it might worth be having a install of a few of them to see if you can get the game out of it that you would enjoy.
