If you're going by MTOW, then yes, the 752 beats the 77L weight/thrust:
B752: 255,000/43,000 = 5.93
B77L: 766,000/115,500 = 6.63
I rounded the numbers somewhat for thrust, so the numbers aren't perfect. I'm also not sure what engines the 757s that operate to EGE have in terms of thrust, so I used 43,000 lbf.
OEW on the other hand, the 77L beats the 752:
B752: 127,500/43,000 = 2.97
B77L: 320,000/115,000 = 2.77
Both are incredibly overpowered aircraft that go like a bat out of hell at full power when empty.
You are calculating with only one engine. And just to illustrate the ratios of some of the mentioned planes in this thread I have calculated some of ratios. These numbers are all based on what I have been able to find online.
As with regards of OEW, it is try that 77L is better, but I have never heard of a plane taking of from any airport only based on OEW. No pax, cargo, fuel, crew? No. Especially from EGE.
