My thoughts on the stages so far:
9. Spiral Mountain (): This is the only DLC stage I actively dislike. The rotation gimmick when hazards are on can be interesting, but it also gets disorienting for me. Hazardless is just awkwardly shaped, with the little corner on the right side and the huuuuge open space on the left. Honestly, I wouldn't mind it as much if the wooden platforms at the beginning didn't leave forever. It's just really awkward to play on.
--- big gap here ---
8. Garreg Mach Monastery (): I'm not a big fan of walk-offs, but design-wise I'm happy with this. Fire Emblem stages in general have been kind of weird because the franchise doesn't have too many iconic locations with distinct designs. (Or at the very least, the grid-based gameplay makes it harder to give us locations that would work as Smash Stages without some major creativity.) Arena Ferox is a real place in Awakening, but the stage layout is more or less original to Smash. It's nice to see a Fire Emblem stage that's an actual location from one of the games, even if I only play it on Battlefield or Omega form.
7. Spring Stadium (): This is an enjoyable stage to mess around on. The ceiling panels are a small addition, but one that can lead to some really funny interactions. The jump pads with hazards on are also a fun little mechanic. I don't have much connection to it as a location, but it's a fun time.
6. Cloud Sea of Alrest (): I love the Cloud Sea visually. The Leftherian Archipelago was easily my favorite area in XC2 because of its integration with the Cloud Sea, so I'm happy we also got the Cloud Sea as a stage as opposed to one of the individual titans. (I am a bit sad that Leftheria isn't included in the background Titans, though.) In terms of layout, Gramps can be a bit unwieldy, and the way it's hard to tell where the ledge is as he's moving reminds me a bit of Spiral Mountain, but aside from that it's pretty good. I was worried about it being harder to see your character when you go below the clouds, but I think the silhouette approach they did worked well.
5. Yggdrasil's Altar (): I enjoy the background visuals of the stage, and gameplay-wise it kind of feels like Big Town & City -- one long, flat stage with platform layouts that cycle in and out. It was a much better stage for me back when I played
, since I had big, stage-spanning projectiles and could fly around whenever I wanted, but now that I play more characters like

who don't have that, it's not as advantageous to my characters lol.
4. Minecraft World (): Surrealness of playing Smash in Minecraft aside, I like the day/night cycles and different biomes that this stage has going on. There are a handful of layouts, but all of them are enjoyable to play on, so regardless of which one I get I have a good time.
3. Northern Cave (): It's simple, but visually stunning. I also enjoy the layout -- the close blast zones and platform layout make doing up-B setups with
a TON of fun. I don't have much to say about it, tbh -- it's a cool stage with a simple but good layout.
2. Mementos (): When I first found out that Joker would be in Smash, I was hoping the casino would be the stage, but honestly I'm super happy with what they did with Mementos. Putting the Persona 5 (and 3 and 4!) UI elements into a stage was a great idea, and the hazards version keeps things interesting with the walls & ceilings coming in & out, along with the trains whooshing in below.
1. King of Fighters Stadium (): The wall mechanic is unlike anything else in Smash (aside from I guess Home Run Contest's walls for Sandbag) and provides a completely different way to play. Also, while I don't play Fatal Fury or KoF much, I can see the love that went into all the stage cameos. While I go back to some of the other stages more, this one has to be my top stage because it's basically a separate game mode entirely.
