A lot of people are high on Kingston right now due to his AEW work (and rightfully so), but he's been a great wrestler for roughly 15-16 years. Moreover, he's frequently hit spectacular highs during that period (e.g. the all-time great rivalry with Hero, the Ian Rotten feud in 2005, the Cesaro feud). He's an all-time great at selling, brawling, and strike exchanges. Plus his range is sufficiently wide enough that he can be plugged into a lot of different situations and produce something engaging. Right now I have him as a top 20 contender, but there's a good chance he'll finish in my top ten if he adds a few more great performances to his body of work.
