Top of the list for me is dear Sviatoslav. I love some of his performances, but his style - to me - sounds very brick by brick. I respect and admire him immensely and some recordings I love, but overall - while he impresses me, he seldom moves me.
Glenn Gould is another mixed figure for me - I love a lot of what he does but a lot bores me. It’s a flip of a coin with him. But I admire him immensely and as a musical personality he may be my favourite to hear in conversation!
I’d probably say Sokolov. There are others, but he’s top of the list. I love him in some things, but overall he doesn’t do much for me.
Lots of em I’m afraid.
Gilels
Hofmann
Argerich
Grosvenor
Ginzburg (pozz)
I also don’t like Gould, but difference is I dun rezpek him eithah 
Ashkenazy
Gould.
MAH.
…it felt like lots of em, but even list assisted I actually can’t think of any others. Several more in the Gould cat though. I suppose present day Kissin might be another, but I think he might rather be one I like more than I respect. He’s turned ugliness in to an art form, but yet I find him curiously compelling (since late 2011 or so).
Hambourg and Cherkassky also in the reverse cat. They were lovely weirdos. 
Kissin and Hamelin as well
Probably da Pletnev. Except for da pedo sheeyat
