Hard question to answer because it varies so much. Biggest converter this month is Spin Palace but very low income. I love Havana Club for whales but FA decided to no longer promote it. FA casinos for us hold the best retention by far. The next biggest converter this month is RiverBelle but commission is low this month for some reason and with the Belle Rock Buddy problem that was just exposed this month you might want to hold off until that mess gets resolved.
I prefer casinos that have great retention to conversions.
