This is an interesting question and here is my current list. It changes a lot though.
#1 Alexander Morozevich (Favorite player. He has an enjoyable style though one I don't follow myself. His insights on the game are fascinating and thought provoking. He keeps things interesting and creates great games. I cannot find something to dislike about Morozevich.)
#2 Daniil Dubov (Dubov has gotten more and more interesting. He plays like Tal more recently, tries sidelines and tricky imbalances, keeps pieces active, and he continues to advance chess in a very strict theorized era.)
#3 Vassily Ivanchuk (Ivanchuk is perhaps the most interesting player of all time and his wacky and out of the blue ideas and play gives him a lot of respect for me.)
#4 Mikhail Tal (Tal is incredible and created the best tactical play ever overall in chess. He is a delight to watch and a value to learn from.)
#5 Paul Morphy (Morphy has grown on me a lot and I love his ability to bring everything together and crush his opponents.)
#6 José Raúl Capablanca (Similar to Morphy, Capablanca's ability to bring it all together positionally more so is a beauty and graceful gift to players of all times to admire.)
#7 Tomi Nybäck (Nybäck is a creative but solid opponent who unsurprisingly outsmarted Carlsen and competed with many other strong players. He is not perfect and has fallen recently though he is not interested so much anymore in chess but at his best, he's the king of the game.)
#8 Luis Paulo Supi (Supi is the kind of player who moves and makes you think why didn't I think of that and he is getting slowly better crossing 2600 about a year ago and he has shown his strength in Blitz defeating Nakamura, Carlsen, and Nepomniachtchi. He's a guy I want to see improve and reach 2700.
#9 Ulf Andersson (Andersson is a player I recently discovered and he adds a lot to the game of chess. His beautiful games and wisdom in endgames is very insightful and a gem among the community.)
#10 Boris Gelfand (Gelfand is a very knowledgeable player in some strong openings and he is often very enjoyable to watch. He gave Anand as good a fight as possible only short a point in tiebreaks (Carlsen defeated opponents that he played in world championship tiebreaks 3-1 and 3-0 so let Gelfand's achievement of 1.5-2.5 sink in.) He has lost his touch now in his older age but he was at his best a positional powerhouse.
