I really don't see any Pearl haters. I mean, sure, during Week of Sardonyx she got some shade, but that's because she fucked up, and deserved some criticisms for what she did, but she's considered one of the best characters on the show. No one messes with Bird Mom.
It is interesting to see the three gems' character developments as the show goes on, because we see Pearl as being the one that is always organized and knows exactly what she's talking about to seeing where she feels like she's broken and incomplete and doesn't know what to do, and then we see Amythest who is just all loose and carefree and a bratty sister sort of character to where we really get to see how much she doesn't like herself and how she's acting less goofy all the time and becoming someone that is becoming more level-headed, and of course Garnet who is quiet and seems to be the leader and alway acts as the mediator to where she literally falls apart about what happened and how she might be a perfect relationship but there are still flaws and there are times where she can't always be keeping her emotions to herself.
I feel like Pearl doubts herself a lot, and I'm sure when we get the backstory about what being a Pearl means we'll understand even more about Pearl and probably the struggle it is to be her own gem.
