Stacks, maybe you get awesome RB as nova at full ring, it kind of sucks at 6m (about 25% for me since I put in lots of money in the pot) and BLOWS at HU. I don't know what wonderland plays...

euro rooms are probably the best for fishyness and RB
but clearing the $600 deposit bonus at tilt is around 60% rakeback (50% rb from bonus + rakeback - MGR from bonus) so you can just clear that and move to stars
and while you're clearing that you'll get ironman end-year bonus and some FTP points that are worth less than stars points but are not worthless by any means
