I’ve tried both. Ben is Chinese, a little on the beefier/husky side (not muscular), maybe late 20s. He was pleasant and the massage was OK but will likely not repeat since I believe the other therapists are a little stronger.
Sam is Russian, shorter skinnier guy, maybe mid 20s. Nice guy and gave a decent massage. May see him again but still feel like Sergey, Brandor, Ivan are better options.
