I find it's easier to work with the post-fader option, as I use my DAW faders to mix, and I would like that to affect how much signal gets sent to the reverb as well.
It depends on the reverb and whether or not the track is relatively center in the stereo field, but sometimes I add stereo widening to push them away from the middle a bit. Not too far though, as it may begin to sound unnatural.
Also, there are cases where sidechaining the reverb to the original signal can cause a cool effect, but I don't use it too often.
