This is how we feel also, Jurassic and Hagrids are our 2 favorite rides anywhere and we enjoy pretty much everything they’ve built since the original HP (minus FJ, Kong, and FF) but we still struggle to fill a whole day at the parks individually, we find we can get a park hopper and do them both in one day.
The recent stuff is miles ahead of the old stuff, which is promising for Epic.
As for value the Uni hotels are usually cheaper than Disney but they aren’t cheap, when we stayed at Aventura we paid $220 a night, much cheaper than the $300 a night we paid for POFQ but still not cheap.
