Probably Keeley just for volume of hardware. The only thing Mu has over her at this point is World's gold, though if she wins that this year Keeley will have definitely moved past Mu in this discussion
Hodgkinson Olympics: 1 gold, 1 silver World Outdoor Champs: 2 silvers Diamond League wins: 8 Diamond League Final wins: 2* (Mu got a wild card for the Final and won but Keely the DL for the year)
Mu Olympics: 1 gold World Outdoor Champs: 1 gold, 1 bronze Diamond League wins: 3 Diamond League Final wins: 1* (see above)
Of the two 23 yr-olds, who has the better resumé of all time as it stands now in the summer of 2025??

Slight edge to Mu, more heavy hitting hardware and more range. Better at 400, better at 1500, slightly slower at 800m despite not really going for a record.
2 golds always beat >1 gold especially head to head
World Junior record 800m
Keely has consistency and volume in her favor with more medals.
Also, I think it's important to note that those Olympic gold and silver medals by Keely are from two different Olympiads, which seems more impressive IMO. Also, they were done in an individual event vs relays.
E.g. people say Gabby Thomas is a three-time Olympic gold medalist, but that sounds kind of misleading in a way. Two of those were on relays and they were all from one Olympiad, (which was missing quite a few past world champions if we're being real). The point is- I think it's harder to podium in two different Olympiads than it is to win two medals one Olympiad.
Good summary, although you omitted Mu's Olympic gold in the 4x400m relay. That should count for something.
Here are a few more metrics we can consider:
PBs from 400m to 1500m
Keely: 51.61, 1:23.41, 1:54.61, 4:30.00
Mu: 49.57, 1:22.74, 1:54.97, 4:03.44

Head-to-Head Record
Mu has the advantage 4-1.
I think the head-to-head thing is also kind of misleading because it's not Keely's fault that Athing has lost to like 10 Americans each time at USATFs in '24 and '25 and can't even make the team to hold a head-to-head matchup against Keely. Otherwise that score would probably be more like 4-3.

This is so disingenuous, unless you genuinely believe Keely could only run 4:30.
Maybe my bias is showing but there seems to be a real double standard where medals are all that count... until it comes to defending a US athlete, in which case any metric us fair game

I'm sure Keely can run the 1500m faster than 4:30, but I don't know if she can run faster than 4:03. I think it's fair to say Mu is the better all-around runner across multiple distances.
I've always used a comprehensive set of metrics in comparing athletes regardless of country. Check out my analyses of Bekele vs Kipchoge.
By your logic: Keely could win every global 800 for the next thirty years and run 1:49, meanwhile Athing could fail to get out of the first round at every USATF outdoor championship and never make it to worlds or Olympics again.
But Athing > Keely, because by your logic, their lifetime record against each other from 2021-2022 is 4-1 Athing.

If Keely wins Gold this year it will definitely tip the contest in her favor.

So no, it's not "end of thread."
I mean its obviously a bit hyperbolic. But when the Olympic golds, overall medal counts, and PB's are so close head to head record should come into play for now. If Mu never gets back to her old level and Keely then dwarfs her in the more important things like medals for the rest of their careers then of course no one is going to care that Mu beat her head to head for a few years back when she was good.
Has Keely ever won a race that Mu was in? No, never.
Has Mu ever won a race that Keely was in? Yes, including an Olympic final, a Worlds final, and a Diamond League final.
Keeley doesn't have a better head to head record because Mu can't even qualify for the Olympics or World Championships now. It's not Keeley's fault that Mu was hasn't shown up to any big races in 2 years.
Keeley was the 2nd best runner in the world for 3 years, and now the best runner in the world for 2 years. Mu was the best runner in the world for 2 years, and hasn't been in the top 50 since.
