179 has the best frequency.
96 probably second.
74 is the bus service which has in sgwiki has the highest number of
buses deployed on it. 74 freq in my opinion is probably
third.
Not forgetting 25 too. 25 is probably forth because even in sats
and suns and off peak, the freq are not bad. The buses come at
regular intervals due to the short route and high demand along the
route.
8 in my opinion has not a bad freq too.
Other trunk services with high freq in my opinion.
9, 24, 27, 60, 70 (only during AM peak), 72
Feeder services
242, 243G, 243W, 225, 222, 291, 293, 261, 238, 334
That's all I can think of.
For SMRT,
trunk services
190 (best obviously)
854 (next best)
67 (freq not bad)
Feeder service
804, 806 (best freq freeder services)
300, 302 (not bad)
