For now I think the strongest force user, going just by feats from movies, is Palpatine.
Notice his fight with Yoda, you remember he tosses a pod at Yoda and Yoda needs moments of concentration, etc. in order to toss it back. Compare this to Palpatine easily chucking senate pods all around the room. He just TK'd shit with ease. Remember Yoda lifting Lukes ship? Not instant, needed some time. Palpatine just Tk's shit with no charge up needed. He levitated multiple senate pods with ease.
Strongest physical force user, has to be Vader, if we go by just movie feats.

He was like the Star Wars Superman. With Superman you just put the word "super" in front of something and boom, shit went down. "Super weaving" exists. I f*cking dare you to prove me wrong. It is a legit thing.
Luke just has the force version. "Something something black holes something something the force".

Luke's display at the end of TLJ was an unprecedented display of mastery from what we've seen in the films. Though I guess it may not be more "powerful" than what we see Sheev do.
Yeah, I'm going with Sheev no matter which canon we use. Yoda as a force ghost lightning striking a tree isn't really a feat. And even if we accept that as one, it'd be inadmissable as Yoda is one with the force at that point. Luke's new #1: feat as of disney canon is indeed impressive, and yet limited in actual utility. It's a force projection, but nobody knows if it could do actual damage.
That leaves Palpatine's galactic level decades long force manipulation under the jedi's nose as the single biggest feat of the force in the movies. Snoke, Rey and Kylo, and even Vader don't really have anything to compete with that.
If we enter non movie territories, and EU... well that is a whole different set of circumstances, as we get into territories such as Nihilus and Starkiller and all that stuff.
Plus tree's aren't evil, why harm them. I thought he is supposed to love Wookies. They have big trees on their planet. Chewbacca is shedding tears over the tree. I know it.
Still I do think in the EU he put a dudes soul into a tree too. Why does he hate nature?

Given the OP states both Mentally and Physically, I’m gonna go with Luke. In his physical prime he overpowered Vader. In TLJ his Mental feat is the best we’ve ever seen.
