A good coverage.
Some extra thoughts from my experienced there.

Nana is pretty spot on, overall it's the best for novices, or if you want guaranteed experience and quality service.
Patpong is my favorite, as I'm an explorer and that's where you find more gems in the rough, new girls, and a generally more relaxed atmosphere.
Cowboy is for visuals, walk through and get out, it can be scam city there, tho there is one I always stop AfterSkool, more below.

Two extras for people looking for things different...
In Patpong, there is a kink gogo, BDSM shows and stuff, BarBar Fetish Club, if that's your interest.
In Cowboy, AfterSkool, get a semi public bbbj, one girl, even two as that's how they prefer, at the naughty corner end of the bar.
You're semi hidden from the bar, by what goes on below the counter, but fully on display for anyone walking to the toilets.
The punters sort of leave you alone, but the bargirls always stop, watch and make comment.
I've even had a bar girl sitting on the counter, knickers gone, me standing, dining, whilst facefucking one on the floor backed up against the bar.
