Coco, tempgf and AF are the best bang for your buck - so many options, great prices and service. It’s pretty hard to pick a number one between them. Also, if you’re not into Asians AF probably drops a tier.
1122 is a tier below those imo b/c it’s a bit overpriced for the quality of girls, but there is a couple gems there.
blush collective and dollhouse are the most pricey agencies, but the girls are mostly modelesque 7.5+ though - so it’s top tier appearance for higher price.
IMO hard to justify given that service and everything else is similar to the other agencies, so you’re just paying a hefty premium for looks, and tbh the other agencies even have some lookers.
vancouvervixxxens is pretty good too.
