We hit so many shots that are different.
Some will so no, they are all the same.
No, not really & not in reality. That is one deluding one's self for psychological reasons or being told to treat them as such for psychological reasons.
We hit many different types of shots. Therefore I think to approach each one the same is not being realistic.
The last 5 years or so I have done away with any stroke other than the actual stroke.
I set the tip with the cue aligned & then make the stroke, most with no pause.
Then there are certain shots that I do the same thing but do make a distinct very short pause & a VERY deliberate stroke.
I think whatever one does should "fit" them & NOT be a dictate or any kind of best practices kind of dictate.
If it does not "fit" one & their personality it can be just as much of a detriment for one individual as it can be an aid & asset for another individual.
And I certainly know the physics that a change of direction involves at least an instant of pause, but THAT is not what I think the OP is asking about.
I think if one does not know themselves in this area, they should experiment with both & do what works best with the best results for THEM.
Sometimes what feels best or seems to work best is not always the case or not even the same thing.
On should pay very close attention during their experimentation & perhaps revisit it after the initial decision from the first experiments.
I sincerely think that if one pays very good attention they might find that different types of shots may be better suited to either one or the other & they may wind up doing it both ways with one way being their predominant way & the other for certain shots.
Best Wishes to ALL.
No matter ones personality or whether or not they want to conform to a set pattern everyone needs to relax certain muscles and contract others to stop the back stroke and then start the forward stroke.
I have a pause at both ends, first at QB making my go/no go decision on alignment and then a short pause at transition from backstroke to forward stroke.
