Topic: What's the best Mahjong game available?

There seem to be a ton of them. With not a single one reviewed I have no idea what to choose.
I like Mahjong games, so a little advice on which to go for would be much appreciated.

If the fanservicy elements don't bother you, Hot Gimmick Cosplay-Jong is pretty addicting. Rather than a "mahjong solitaire" game, which is what you usually see over here in the west, this is the real deal.

It took me some reading to figure out how to play it, but once I started to get the hang of it, it was pretty fun.

Not sure what the best solitaire title is, if that's what you're specifically looking for though.
