Do you prefer? the variants all looking the same like doctor strange or different like Spider-Man?

Doctor Strange is so powerful he got to have rizz in every universe

Damn. This is a great question.

I guess I would love some combination of both. It's really fun to see the same character with a varied number of personalities and/or physical features (slug-like, half-android, etc...) but having the multiple Spider-Men as well as all those different Lokis was super god damn fun.

If I had to absolutely choose one or the other, I guess I'd have them different just because that really opens up the potential to the point where the imagination is the only limit.

I think you've got it. Loki did it best having some be versions of Tom Hiddleston, and some be wildly different. I think that's how it should be
- I think it would be interesting to have our version be the non-standard more often. Like Miles is a unique Spider-Man, where most are Peter. Pavitr has a crisis in the comics because of it.
  
  Like what if most Lokis were alligators? Or most were legit Frost Giants and he was weird for being human-looking.

I think that in a full-on multiverse where absolutely anything is possible, you'd have to expect some of both now and then.

Perhaps another way to look at it is, what are the chances that you're going to encounter a more similar universe, vs a less similar universe? As far as I'm aware, none of the MCU multiverse stories have necessarily attempted to answer that question, as yet... but if I were to take a crack at it:

I'd say that it largely depends upon the method used to traverse universes. If your method is intelligently directed, you could assume that encountered universes are more likely to be similar to your own universe. If on the other hand, your method is more random and chaotic, you're more likely to end up someplace completely unfamiliar.

But then again, with characters like America Chavez -- who directs her travel with her own mind, and still has greatly limited control over where she ends up -- the entire notion of what constitutes "intelligent direction" kind of comes into question... so it's all rather too complex to analyze effectively, isn't it?

its really just indicative of a larger issue with the multiverse in the MCU

which is that the multiverse in the MCU actually seems to be, like, half a dozen different iterations of the concept that function and look completely different

its like having a setting with 6 different magic systems that do the exact same thing and yet have nothing to do with eachother

I agree with the people saying that it's probably more realistic to have a mix of both, but honestly, I like when other actors play the variants best. I'd have loved to see some other actors' takes on Strange in MoM.
