The reason there are not a ton of generics in the game is because they are not as fun....
Hate to break it to you but the abilities of unique pilots are allot of fun and push comes to shove you pick the ship that is more fun.
Competitive players approach list design from the reverse perspective: you use the most broken overpowered ships and combos that can keep up with all the other broken overpowered combos.
Generics don't qualify so they sit on the shelf, it has nothing to do with the list being "fun". Personally I really enjoy flying jousty control lists on occasion, but they're just not viable with generics.
All things being equal (if they are indeed balanced) then you take the fun ship... so in a world of balance generics see less play.
I also strongly disagree with you personally on almost all things x-wing including jousting lists being none viable with generics, for pure jousting i take generics... 5x Kihraxz is my gold standard for pure jousting... and it works very well regardless of whatever math crap you have done on it. You analyze ships in a vacuum and without key components like there dials, and how they fit together with other parts of the fleet and end up poisoning these forums with your opinions on what is good and what is not.
I think, fun and new has a huge impact on what is winning in the meta, at least it does in my local area... regionals was 3 days after a wave 8 came out over half the lists were wave 8 ships that no one had flown yet just because they were new and fun the top 2 lists were wave 8 lists. I tossed my list out that i had been practicing for months in favor of 4x barons of the empire because they were new and shinny.
These are just my opinions of course. I do not mean to be rude Majorjuggler I just find people using your data all to often to rule out ships without ever giving them a proper shot or using them correctly within a fleet, ignoring things like individual player play styles is a huge mistake there is no list of what is good and bad as each player will have different results.
