VIOS coz:
1. Vios is cheaper
2. All Toyota has better resale value
3. Toyota spare-parts cheaper whereas for Honda, even if one part rosak, you'd need to change the whole thing so it will costs more (from what I heard la)

BUT of coz the City looks much nicer la, and heard that City's engine not as noisy as the Vios's

SO it really depends on the buyer's preference!
