Hmm. Yes and no. It really depends. But I would lean to yes.
I was talking with Jason England when he was in town, and he pointed out that if you are doing the ambitious card and you use a pass that is unnoticed by the participant vs a double undercut, though the effect is the same (card comes to the top) they have a different understanding of what just happened. The double undercut handling looks like you are good manipulating a deck of cards. The pass looks like you did nothing, but had the same result, which is imo more impressive.
Sometimes more procedure is more impressive (think Sam the bellhop without the shuffles lol)
And then of course if the look is the same, (using a diagonal palm shift vs a pass to get the card to the top) then it probably doesn't matter much.
If you are wanting to improve, record your effect done both ways and watch to see which looks more natural and less fishy.
