I did like BGO although after initially what appeared to be decent regular (although little) payouts for a few weeks, once i became a regular the games suddenly appeared to play poorly which i found somewhat odd.
Been trying Jetbull and i have to say very disappointed. Very rare features and when the games do eventually feature i'm lucky to get over £5 or £6 win level which i find remarkably poor considering it often takes £30 or more to even get a feature (with no worthwhile wins in between either incidentally)
Have to say as a very regular player i very much dislike the way most of these online casino games appear to follow a rather concerning pattern...as in as soon as you drop below the withdrawal threshold the level of wins and features clearly drops significantly and it's very rare to get back above the threshold again!
