Overall rural area still the best i.e. wife's hometown at Udon Thani, air is super fresh, people are super nice, food is super fresh although most of the time looks weird to city people like me but if you try it it's actually very nice. The only problem is getting to places, for example getting to the town from wife's home is around 30 mins ride, or getting to some well-known temple is 3-4 hours drive, so without a car it is very difficult or impossible. And because of the distance, that's why you see people from rural area are more relaxed no rush type. Then come to Bangkok, the transport is terrible, the jam is terrible, the culture is terrible, taxi and tuk tuk drivers always try to overcharge if you are not local, Grab is not as easily available as in Singapore, and the worse is the pollution, if you take tuk tuk and get driven across a busy street you will know what I'm talking about, it is just horrendous. And most Thais in Bangkok are not as friendly as tho...
