Putting aside that both faction Garrisons are automatically shit because of the forced Human/Orc aesthetic, I think I like the Hordes layout within the walls more, but the Alliance has a better exterior.
Frostwall's snowy landscape and bonfire pit is extreme comfy. It's more rounded as it dipsinward with the important buildings outlining it. Less boring than Lunarfall being built like a lane/street with a fountain as the central focus.
Also Frostwall Tavern is a way better building than Lunarfall Inn.
But outside the walls, Lunarfall's got a far better fishing pool and view at both ends. Outside the main gate has a nicer view of Shadowmoons grassy landscape. Even has some of the trees still standing beside it for the Druids to gather in for whatever shit they get up to. Whereas Frostwall's got a cave for their pool, which they also decided to have their garden in for some reason, sure the lack of sun isn't an issue on those flowers. And outside the gates is immediately a lava pool and jagged rocks and shit. Which, like, I get it, makes the place way more defensive, but they don't even utilize it with some old Alliance/Horde themes. Druids gather by the Alliance Garrison because nature stuff, could've had Shamans gathering by the rocks/lava and such for a heavier focus on the elemental landscape. Lacking them just makes me think damn, the Garrison would've looked way better in other places of Frostfire.

As a takeaway for housing, it's nice that you can pick your location in that regard, even if your locations are still limited and most people are probably gimping their preferences just to be with guilds/communities. Still fucking sucks they're sticking with Human/Orc themed by default though.
Even if other themes are incoming, big bets on they're not coming all at once. Tossed out one by one at best, and naturally Elves would be first because 'expansion theme', and copy/paste easier from the human theme they can just throw gold/purple over.
