I will summarize it for you. There are indeed more FCP users than there are PP Pro users, at least for a while.
Nobody seems to agree on either ones market share…but, anybody who tells you flat out that one is better than the other usually doesn’t detail his/her answer, and most likely hasn’t pushed the software enough to even understand the limitations of either one, and they BOTH have limitations. I think that they both have some issues, and you are bound to run into them at some point, you just learn how to live with them.
Overall, FCP users probably run into as many issues as PP2 users.
