I don't want to play a multiplayer game with hitches every few seconds. You can't fix this with "smoothing" with deterministic lockstep model but you could fix it by increasing the playout delay buffer from 100ms to 250ms, but that's adding another 150ms of latency to the player experience which is less than ideal. It's a much better option to use UDP in this case to get the best experience for most players.
