For me, it's:
969( fast, direct link to the East, now resplendent in my favourite
Volgren 0405Gs and Habits with plenty of 0405s to pass
around..)
36( super convenient link from city to MArine Parade and Airport,
got my favourite single deck on SBST too: The Volvo B10M MkIV
DM3500 )
806( Though the feeder bus service doesn't run on Sundays and PH
, where else can get a bus service with Habits departing
every 3-5 minutes during morning peak with friendly bus drivers? As
I know, the Woodlands services don't get near it )
