Welcome to B&B!
Blades are a very YMMV thing. You need to find the blade that is a good marriage between your face/beard and technique. If you're near the start of DE shaving you may find that the perfect blade today is not necessarily the perfect blade for 6 months from today.
I prefer some soaps over others, but I can get a fine shave from just about any soap. I strongly suspect that your years of experience with Proraso are the reason it worked better than the new soap. It usually takes me a few days to hit that perfect ratio of soap to water with a new soap. The first day it might be pretty good, but just a tad too thick. The second day, of course, it's pretty good but a tad to thin. I eventually find the sweet spot. They are not all the same and they won't all produce exactly the same shave - or why would we have so many choices - but it may be worth a little more experimenting before you dump a soap. There is no rule against test lathers either, so experiment away.
