As someone who enjoys painting more than gaming and wants a faction that’s fun and unique to paint what xeno faction would you recommend?

I’ve already got a large salamander force as well as a large amount of imperial guard and like 1500 points of death guard, I want to try a xeno faction and am torn as they all seem equally cool so on a fun factor of painting them what would you recommend? I don’t want to look stuck up but I think my paintings quite good so don’t worry if the faction is difficult to paint well, thank you for your recommendations, the only ones I can’t really see myself wanting to paint are necrons and drukhari, I love the look of tau and eldar but was told their ranges aren’t very big, I love the idea of tyranids but they don’t seem to unique to paint, I like orks but am shit at kitbashing, anyways Reddit please decide for me, thank you
