W Koh Samui vs Four Seasons vs Phulay Bay

I was hoping maybe some here might have some experience at all three of these hotels. I have booked all 3 for the middle of May for 2 nights each, before I head to Japan for a week (staying almost exclusively in Moxy hotels) before finishing up a week in The Sira, in Lombok.

I’m really curious about the difference in these hotels particularly the W and Four Seasons. I can see Phulay Bay is a totally different hotel to those two but still curious. Thanks.
