I have a lot of favorites [like the ghast, enderman, slime (if I'm not trying to build something)] but my least favorites are bats - they're super annoying and useless - and skeletons, like many others
I hate slimes so much due to a traumatizing experience I had when I was younger. I went into Spectator Mode, spectated a slime, and made the mistake of dismounting. That's why I always stay at least 50 meters away from the buggers.
As for favorites, I love the blaze due to the sounds it makes and its appearance. I can very rarely bring myself to kill them.

That just broke my heart, bats are may favorite. I like making up stories about their orgins, and it's really fun.
My least favorite has got to be Guardians. Under water fatigue inducing laser shooting fish? Ouch.
My favourite is the parrot. It flies or sits by your side looking awesome in various different colours. It has good taste in music, good at dancing. The noises they let out are actually quite alright as opposed to other annoying mobs.
The worst mob is either the bat, it is absolutely useless and gets in the way, or the phantom, I mean... Does anyone actually like the phantom.
Also I don't understand why everyone dislikes the skeleton. Without it we wouldn't be able to acquire music disks...
actually, I have two favorites
#2 spot goes to wither skeleton. mostly just because I think they are cool
#1 spot goes to endermen. I like them because they don't really attack you unless you give them a reason to. (and it amuses me when people get triggered, and endermen definitely get triggered.
least favorite: witches. they are too OP. the poison gets you to half a heart, then they give you a potion of harming and it's all over. once I was digging out an area to make a farm but a witch in the tree threw a splash potion of poison at me. I ran away to tell my friend, but when he came, the witch was gone.
Favorite: pigmen, iDK why, I just really like them. Some lightning striked my pig farm so I got a bunch of pigmen in my world, I captured them and made a house for them with a bunch of nether blocks. It was pretty big.
Least favorite: ghasts. I hate them. Simply hate them. Worse then creepers. These bois got me killed when I didn't have any arrows with my bow iDK how many times.
