Yes, they used to be the gold standard site by a distance, particularly with regard to customer services reputation. The online response time nowadays is just as bad as anywhere else, although the software is still pretty slick.
I played PLO against Dave a load on Full Tilt, Heads up and 6 max. I was also lucky enough to play PLO with him at Dusk till Dawn, not long before he passed. Great bloke.
Played regularly about 20yrs ago for a few years, online only, other than the odd 'poker party' with mates. Gave it up due to the amount of time you've got to commit.
There's a place around the corner from us with a sign that says "Liquor in the front and Poker in the rear". I'll give it a whizz sometime.
