I've 100%ed a lot of games, and I do tend to enjoy each one I 100%, or else I probably wouldn't have 100%ed them to begin with, lol. Some more memorable ones include Metroid Prime, where somehow I always kept missing a missable scan or two while running through it, until I finally managed to 100% it fully (scans + items) during my umpteenth time of playing it, lol. It was gratifying 100%ing Death Wish in A Hat in Time's DLC, due to the difficulty of it. 100%ing Red Dead Redemption was also really great to accomplish just due to how large the world was and how much there was to do in order to fully complete it. 100%ing Banjo-Tooie was special due to it being the first game I ever owned, thus having a special place in my heart. Lastly, the first time I 100%ed Majora's Mask was wonderful, since I remember having difficulty getting the last heart piece I needed (the Clock Town Shooting Gallery Piece of Heart), and so to get it that one early weekend morning was super satisfying and also just a huge sense of relief. Of course, nowadays I 100% MM in every playthrough I do with little difficulty, haha.
