I'm not sure how you arrived at your conclusion that OSU would be a better training environment but I very strongly disagree based on real world results.
I didn't say OSU has better head-to-head wrestlers. I said it's a better overall environment and that OSU has more than adequate wrestlers for Gilman to use as a barometer. With OSU's roster/staff consisting of Fix, RBY, Forrest, Spratley, Figs, Sakamoto, Hughes, McComas, Kennedy and Sakamoto you can't tell me that Gilman is going back to PSU for training partners or to use LL as a barometer. Couple that with the fact that Gilman doesn't like training with the competition, then PSU would be less than ideal with LL (#2 in US, likely Gilman's ceiling), Blaze (#2 at 61) and N. Lee (#1 at 65)...couple that with the fact that Gilman would have to go 57 for Olympics and would have both LL and Ono in the room. At least at OSU, his only potential competition would be RBY/Fix who he has a better chance of beating than the others.
And, regardless of better wrestlers, the plethora of different looks that each of those - Fix, Figs, Sakamoto, Forrest, RBY give is certainly an advantage. All of this was to say, the possibility of competing again and LL as a barometer is not the reason. It's purely because he was booted from OSU and PSU offered him a coaching position. If the left PSU to go to OSU, then he probably considered all of the above. And if the strength coach at OSU said he can grow into a legit 65, then training at OSU is as good as it gets (considering Blaze and N Lee are at that weight). In summary, regardless of best wrestlers, the room at OSU for an elite freestyler is damn good, and rivals PSU.
Someone mentioned that Ono is #1 in the world, and I responded there and said, if that's what he is looking for then he should consider or have stayed at Iowa where you have and had Lee, Tom, Terry, Ayala, DeSanto, DeLuca. Lee was always that answer. And you can't say Ono is better than Lee based on one match, up a weight with no scoring. And Lee speaks English and can converse.
Training environment is not dictated by best wrestlers - many PSU wrestlers performed below seeds at NCAAs, and Dake, Snyder, Zain and Brooks could certainly have had better showings, you know, "based on real world results". When you recruit and pay Snyder and Dake to come to NLWC, their past results don't count for PSU...but their current shortcomings do! BTW, Kennedy's results on the world stage are remarkably similar to N Lees. And Forrest and Blaze are very close in talent. So, let's not exaggerate here.
Oh, and in your greater than/less than scenarios above....don't forget that in one side of the equation you list 3 wrestlers (PSU) on the other side, you list 5 (OSU). That difference alone is huge when looking at training partners. And what about Figs, 3x HS state champ, NCAA champ, Junior National champ, Junior world team member, Junior Pan Am medalist....
Seriously how do you sell a room with Fix, RBY, Figs, Kennedy, Forrest short when you're talking about Gilman. Honestly, I would take any of them over Gilman head-to-head. Gilman is not in his prime.
