Favourites
Toa Payoh - Aircon, the good there iis great and the location is
great, as it is nar to many shops and the MRT station 
Jurong East - Childhood interchange... spacious and colours like
the MRT station, and not to mention its near the MRT station/Shaw
centre also.
Bedok - Oldie interchange but has good food according to many
people. Near MacDonalds, the NTUC.
Sembawang - Airy and near the Sembawang MRT
Ghim Moh - A very unique and small place, but its near some great
food and market places.
Hougang Central - Near the KFC 
Punggol - Lonely and quiet
Kent Ridge - Easy to go to.
Bukit Merah - The interchange has buses and its the only remaining
INTERCHANGE to be not near the MRT.
Yio Chu Kang - It's just outside the MRT Station!
Eunos - Large space, few services. under the MRT!
HarbourFront - Near Vivocity, Harbourfront Centre, HarbourFront MRT
Tuas - The most quietest and spacious terminal of all.
Bukit Panjang - Great to take photos!
Sembawang Road End Terminal (gone) - Near the park 
Why did
it have to go ?!?!?!?
Detested
Sengkang - Alighting berth is not in an aircon area. Very dangerous
and people may suffer from the carbon monoxide. I wonder how 80,
86, 87, 119, 372 drivers handle the smell and smoke!
Bukit Batok - I just don't like it.. but no reason needed.
Choa Chu Kang - The interchange is going through some upgrading
works so have to walk far to the MRT/Lot 1.
Clementi - The temporary interchange is better than the original
but the traffic timing is horrific and also the interchange is far
from the MRT.
Pasir Ris - Dark and gloomy, even with the sunlight.
Bishan - Dark and buses take up time to leave the
interchange.
Ang Mo Kio (Temp INT) - It's far from the MRT/Jubilee and the
interchange is not even that kind of quiet i like.
Woodlands - No Lift! The first underground INTERCHANGE needs a lift
so that i dont have to just take escalator and that the less
able-ed can take buses too. (applies to 161/168 B9TLs only)
Changi Airport - Similar to Sengkang in the sense people have to
bear with the carbon monoxide. But its worse because no aircon!
Geylang Lorong 1 - The boarding place is far from the road and
dangerous to go when all the buses except 980 turn into lorong 1.
Sometimes the smell is horrific.
Shenton Way - Where is it?!?! Under the ECP!??! The place isnt near
the Tanjong Pagar MRT!
