My friend and i recently got one Automatic (ako yaris, cya swift)

Fuel Consumption (Relax City Driving)
Yaris : 11KM/ LITER
Swift: 8.5KM/LITER

Interior Space
Yaris hands down. Impossible to sit at the back of the Swift

Driving Pleasure (Handling)
Swift, the steering of the Yaris is too light

After Sales Service and Parts
Swift= Forver Casa

Durability
Yaris= Toyota is more reliable, we still don't know if Suzuki small cars are as strong as they're big cars

Re-sale Value
Yaris: You can get cheap 2nd hand 2007 Swifts

Design
Swift design is due for change soon. Yaris not yet

Since this is your first car, it will be better if you get the trusted Toyota brand for less headaches and better fuel efficiency. Pang date mo nalang ung gas savings
