I really enjoy Finlay, but this is someone who never struck me as that great of a worker. Super solid, yeah. Even more than that. But he never put it together to have special matches, whereas Regal did (despite being put more or less in the same position). I had seen some of his most vaunted WWE match, and I was not that impressed. His WCW work is excellent, but he also never found a way to get himself over. And it's not a matter of not getting a push. Finlay winning the TV title early in one PPV in 98 deflated the crowd hard. His New Japan sting in the 90's is mediocre. Way overrated on this list. Would have made my top 150 or 200 without an issue, but I don't see him as a Top 50 guy ever at all.
Basically where I am on Finlay as well. Just never connected with me. Always solid but just never special unless in with Regal. He's a common favorite of many people who's tastes are often similar to mine, but for some reason I've never been able to see the light here.
