I have never been to Bali. But I say anything but Phuket. Phuket is the worst place in Asia I have been to.

Expensive food. Too many trashy tourists (of course I am one of the few un-trashy ones ) but the worst thing that makes it my least favorite place in Asia is the transport situation.
Those awful pickups they call "Tuktuk" that are run by mafia, and charges more for one kilometer than a nice metered AC Taxi in Bangkok charge for 10 km.
Since my last visit I know they now have Grab. But Grab in Phuket add an extra 150 THB per booking on top of the ordinary fare!
Unless you rent a moto, which is not always feasible, transport will eat up a large chunk of your holiday money.

Actually I have never paid bribe to get into Thailand. Or you mean the overstay fine?

Last time I crossed the dannok border there was no Rm2 fee... but lots of signs saying "There is no fee for using this bordercrossing", "Do not pay for crossing the border!" etc..
