Sp is better in most ways than the other fps games. There a decent variety of gameplay in SP. Sometimes the variety is gimmicky like the falling sequence late in the game. MP does not work w3ll for me. Laggy as heck and bf4 is not. I live in Hawaii so its possible bf4 has better server support here.
