You are right that swimming wasn't universally liked/implemented well enough for them to keep it in the series and climbing/mounting provided an easier vertical movement design.
3rd Gen still provided the best new additions to the roster (P3rd adding Zinogre was fantastic too) and those monsters have stuck around except for the fan service and nostalgia potential of 2nd gen.
Tri was them trying new things, which is what World also is. We had a roster mix-up with monsters vaguely similar but updated as well as things like Bowgun customization and the idea of a persistent map you could explore with the Moga Wilds. Some were dropped but some things have stayed.
I really don't care what console it's on, I played FU/P3rd/Tri/3U/4U/Gen. Each game has tried things and some worked, some didn't.
