I disagree on the assumption that Moreno has figured out the power aspect using half a season of data... though I concede that the assumption I made of Kirk re-discovering his earlier power is also based on the same half a season, so... could probably call that a wash. Is recency bias more in play with Moreno simply due to age, unfatness and the chance that he "figures it all out?" Kirk isn't exactly ancient either, I'd say the chances of either one of them figuring out the power is roughly equal.
I would agree Moreno has more raw pop, but maybe like 55 vs a 50 for Kirk? Not a huge gap. I'd probably put 40 grades on their game power. Their HRs/PA will probably be pretty close going forward. Kirk is currently 1 HR every 38 PAs, Moreno is 1 HR for every 56 in regular season, 1 HR for 45 PAs including the postseason, though SSS caveats apply. 2023 seasons standing alone, Kirk was 1 HR every 53 PA, Moreno (including playoffs) 1 HR every 41 PAs. Still not quite to Kirk's career average. I suppose the overall feeling is which side gets more weight, recent results for Moreno vs early results for Kirk.
Kirks earlier career power also came at an earlier age then Moreno, 21/22 age seasons for Kirk vs age 23 season for Moreno.
I also make a bit of an assumption on Kirk that he will put some effort in the weight loss and become a less s***** runner over the next few seasons before his knees give out like all catchers' knees do and put him right back at the floor he is at now.
