Underwater combat is just so much fun. If anyone has told you otherwise you may have fallen for a propaganda campaign to besmirch the good name of Third Gen Monster Hunter. Tri in particular is a really cool version of the game. The online hub of older Monster Hunters, in Tri, Loc Lac City, offers a very unique experience that isn't really offered in newer Monster Hunter games. Wilds does seem to be approaching a weird hybrid between the smaller 4-player restricted hubs and the City/Town styled hubs of older games but from what I had experienced of Wilds' demo it's really not the same kind of deal. Tri, though, is really just fantastic. The "roster" of large monsters in this game is actually pretty small, smaller than vanilla World iirc, but, imo unlike World the design of the fights in Tri far outclasses World's offerings. It's a really great game and it's a shame that it's stuck on the Wii with dead servers.
