Yes, but there is even a mythologizing of his peak ability, to some extent. People regularly mention Komen in the same breath as Bekele and Geb although he was certainly no match for peak Bekele and Geb ended up having the last laugh as well. There are certainly guys that have run top times and either fizzled out in a short time or never won anything big that don't have near reputation Komen does, for whatever reason (I personally think it is only due to that 7:20 and the fact that not many big outdoor 3000s are run any more -- if he hadn't, or if it was raced more regularly, we probably wouldn't hear his name too often).
Noah Ngeny comes to mind as the best example -- he has three world medals, winning gold over the GOAT in the event, he has a WR (2000m, 2:11.96) that is much higher (literally off the charts) than Komen's 7:20.67. He ran 3:43 in the mile. He is 42nd on that list you made that you linked. Worth noting that Joshua Cheptegei is actually 41st on your list, despite 2x WR, scoring better on the tables than Komen, winning more, etc. Cheptegei's 12:35.36 is slightly better than Komen's 3000 WR, and his 10,000 is better still. You can shoes me on that one, maybe, but not Ngeny.
Then there are others that were clearly better that get lumped into his tier, like Bernard Lagat, a many-time world medalist and 2x outdoor & 3x indoor world champion. You had him 23rd on your list. Surely Lagat deserves to be better than a dude whose claim to fame is running some really solid 3000s and holding the 50000 record for a year? Lagat's 3:26.34 has an almost identical score on the scoring tables to Komen's 7:20.67.
