In terms of design, HGSS were not particularly impressive. Johto looked great re-made, Kanto didn't, but that's because Kanto was ugly as sin from the start, can't change that without changing the look. That's just graphics stuff, which has been steadily improving regardless.
Johto got a couple extra routes and it's own new Safari Zone. A good chunk of Crystal's story with Eusine was put in. Ruins of Alph got some cool new additions. Lot's of great UI changes like enabling auto-run. Killer soundtrack, but Pokemon almost always hits the mark with soundtrack; GB sounds are available for nostalgia fags, a nice touch.
It had Battle Frontier which is always a major bonus for the more hardcore pokemon audience like on /vp/- but this isn't as impressive as it sounds as it is a literal copy-paste from Platinum's Frontier.
Now for the bad stuf: Kanto's Safari Zone was removed. The Sevii Islands are left out, despite being established in FireRed/LeafGreen to expand Kanto and help fix the Cinnabar > Viridian level curve. The level curve in general is still as fucked as it was in the original, not sure why they didn't fix that. Certain routes/caves in Kanto were shortened, excusable during the limited memory days of GSC, but not so much at HGSS' time.
Pokemon distribution still sucks, way too many early shitmons all game in Johto and Kanto, and some Johto Pokemon are so rare it's asinine, (Yanma has a 1% encounter rate on only one route.) Johto is still only 60% of a region in game time and content. The Johto storyline is unusually weak for Pokemon, despite Rocket being the villain they are irrelevant. Silver and Eusine are the only saving graces in that department.
HGSS were good games. Were they on the same level as BW2 or Platinum, or even Emerald? Certainly not. Nostalgia runs thick in the veins of /vp/ users.
