Short answer: no, among the gfe amps they are all roughly the same
Long answer: Haven't mongered much in the past year, but pre-covid certain amps had their niche (i.e. Grace Spa generally had thinner/smaller/cuter girls and I think that was biggest difference looks-wise from my experience). Some had more accurate photos, some had more K-girls, etc. Overall, they were roughly the same looks-wise, and you were better off doing your research on here to find a few options that fit your tastes rather than to exclusively go to one spot since rosters change frequently. At each of the top gfe amps I've had girls that I thought were really good looking and girls with whom I struggled to keep it up so it's hard to rank them.
