Microstakes PLO

Hi . Sorry if this has been asked before .
HAve recently got back into playing poker . I am currently playing on ggpoker. My question is , is ggpoker the best site for me to try build up my bankroll or is there a better alternative.
Keep reading that it's unbeatable with there rake system ?
So Basically what sites would you suggest for someone trying to grind up the stakes playing PLO .. cheers guys
