since budget is not a constraint go for swift, for comparison
both are 1.3, hp and torque figures are almost same, both cars lead one another in each but consumes a bit more fuel.
quality wise, swift is much better with alpine audio system, quality door panels and plastics used all over, newly designed body.
safety, though v2 has advantage of airbags but zero chest protection(according to chinese ncap Full Record of Impact Results) makes the protection by them questionable.
drive, though quoted performance figures are almost same, drive of swift is more peppy, grippy and suspension is set right for our country(instead of one instant thump of chinese cars, my experience of v2 and chery qq) the front suspension travels to reduce impact of a speed-breaker.
features, v2 has rear wiper, fog lights and headlamp leveling.(being chinese durability is questionable.)
availability of parts and mechanics for suzuki vehicles all over Pakistan and since less risk of suzuki running away after selling a few units swift is better in my opinion.
