Thoughts on Sugarbabies or Sugarbook

Can anyone share experience with the website/app sugarbabies or sugarbook? I read a comment on the TER Discussion Board that kept referencing "SB" and thinking that might be one of these two platforms. Anyway, if anyone has used either of these before with success, certainly chime in.

Currently, I use P4, Tryst, OH2 and RR just depending on the situation but all have their pros and cons obviously.
