My order of preference based on 5 years experience with all three of them both prepaid and post-paid is:
1) AIS
2) DTAC
3) TrueMove
But the OP wanted best Bangkok city 4G coverage so I had to put my grudge against TrueMove aside and suggest to go with TrueMove.
AIS are starved of spectrum so their mobile high speed data is over-subscribed and crawls to a halt in congested areas during peak-time. Think Asoke BTS on a weekday at 5pm or Siam Square during lunch time.
TrueMove doesn't have that handicap and has always been aggressive in 3g/4g trials.
In terms of post-pay flexibility, DTAC wins.
In terms of all-round service AIS wins.
I only ever recommend TrueMove when someone has the specific criteria such as the OP here.
