>infinite SS Aqua rebattles It has a battle frontier.
>music playing in the wrong placesThat's a bug, not a feature, and should not be praised.
>plus it's censoredSo was the original GSC.
It also added more features:
>Safari Zone with a brand new set of mechanics>An entire new route to get to said safari zone that includes an area to catch the Hoenn box legendaries postgame>Battle Frontier has been added, replacing crystal's Battle Tower>A new and improved set of rematches for the E4 once you beat all 16 gyms>The Pal Park to transfer pokemon from FRLGRSE to HGSS>An entirely new event area where you can get new lore + a sinnoh legendary of your choice>The Pokeathalon, an entirely new minigame set that makes it easier to get evolution items than ever before + offers a ton of new content>New wild pokemon thanks to postgame radio stations>Adds back legendaries that were missing from GSC (the legendary birds) + adds the Cerulean cave and Mewtwo back into the game, basically adding another entire dungeon to the game>Re-adds Viridian Forest + adds a new mossy rock to get leafeon>Adds new areas to Mount Silver including a way to get moltres>Re-adds Seafoam islands as a dungeon including articunoHGSS adds so much that was either not in or missing from GSC that the things you mention are paltry in comparison. It trades stupid pointless faff and straight up music bugs for actual features and content, making the Kanto half of the game more expansive and just in general making for the definitive Johto experience. It is an objective improvement by the sheer amount of content added alone.
