Currently own an iPhone XS and want to make the jump to android, I’ve settled on a Samsung but I’m unsure which to get (I’ll be buying refurbished, if that matters)

Eyeing up the 23, 23 plus and ultra, really don’t know if the plus and ultra are worth the extra money over the base model?

Any input and advice is welcomed as I know next to nothing about Samsungs it android, been an iPhone user for as long as they’ve been a thing but it’s time to leave them behind for a better phone!
