I'm surprised people are listing all of the cool aspects of ORAS without mentioning the DexNav. I thought that was an awesome feature at the time, although I guess maybe in hindsight it's less interesting now that Pokemon just wander about in the overworld?
Anyway, I don't think ORAS should be lumped in with BDSP. While they definitely had their share of flaws and were disappointing overall (relative to how good they easily could have been), they are still good games and did add a lot of great new features, on top of bringing over pretty much everything from XY. That said, I guess I would rather just play Emerald, so in that regard they're in the same boat as BDSP, lol.
This reminds me -- I'm actually really looking forward to playing Sigma Emerald soon, which is a fan romhack that just modernizes Emerald a bit without altering the game otherwise. It adds the physical/special split, reusable TM's and the Fairy-type, etc. That should make Emerald pretty much perfect imo!
