I've seen people shitting on 75M and Great Cave Offensive a lot when it comes to bad stages but to me, they're perfectly fine and playable stages. I actually even like 75M quite a bit, I find it pretty fun to play on generally speaking (love that low upper blast zone, means more Star KO goodness), but I do get why people gripe about it, ladders can interfere with navigation a bunch and the hazards kill ridiculously early (I prefer the 4 version where they phase through you rather than hitlag because you can easily get hit twice by them and that usually means a death sentence). And Great Cave Offensive's lava is fun, plus the low upper blast line makes for funny KOs too, but yeah the bottom parts of the stage can easily be ignored, if only respawn points are random throughout the stage so those portions don't feel like a waste of space.
Palutena's Temple is...I don't really like playing on it at all and I dread it slightly when it comes up on random, even with 8 player Smash chaoticness, especially when you're using a slow, tanky character (also equipped with the tank style spirit). It takes forever to kill anyone because of the immense size of the stage and the multiple caves of lifes (especially on the bottom left area) and CPUs on that stage don't really seem interested in fighting you as much as they...just wander about, causing this stage to be a cat and mouse fight even with 8 characters. I like when stage morph morphs between a tiny stage and the huge ass temple but that's practically it. I like picking it when I want to meme myself chasing after one particular CPU and trying to survive on just one stock in a 17 minute match to the end, but that's about it, I don't generally pick it often because it's simply not as fun as other stages, including 75m, New Pork City, Great Cave Offensive, and Hyrule Temple.
