I really like Bangkok. But are you asking as a place to live year round, or to visit for a short time? There's a big difference.
I have lived in Bangkok and really enjoyed the experience, although I wouldn't want to stay there year round. There are many great things about living in Bangkok: shopping, leisure facilities, access to places like Samet Island. It very much depends which area you live in. I've lived in the Sathorn area and found it clean, convenient and had a great apartment there.
If I had to sum up Bangkok I'd say never a dull moment, it's just plain fun!
