For whatever reason of the common weights 124/5gr bullets have always given me the best accuracy. 133s and 135s do even better in my Glocks. 147+ things open up a little.
There is a distinct difference in recoil between factory 115s and 147s loaded to PF floor, my observation is the latter is also more reliable at making poppers fall. The slide speed stuff is somewhat observable but you're not going to outrun it. How far the sights lift is not very different, how they return is again observable, but the timer won't notice unless it throws you way off, so pick a load and stick with it and it can't.
The last WWB 147s I shot were immediately after my 132PF 133gr load and was astonished at the difference in the recoil impulse, the WWB was stupid soft, FWIW, but I've seen a lot of obvious external QC failures with them so I wouldn't be surprised at a production lot having powder charge error.
If I had to buy factory and was going to just burn rounds at the range I'd buy whatever was cheapest.
For competition I'd probably go with one of the smaller loaders, T1, Minuteman, etc., get a sample of various weights and let the groups decide.
For SD I like the 124/5 class, good accuracy, and from the tests I've seen plenty acceptable terminal performance.
