DSG is anyday better. With 7 speed box, even better. But what Honda provides are paddle shifters which makes the drive engaging.
I give credit to Honda City for engine and Vento for DSG. City CVT with Paddle shifters makes for an no-nonsense buy BUT Vento DSG is value for money and an enthusiast buy.
Keep Vento DSG as option 1 and test drive both cars.
LED Headlamps are better than conventional halogen lamps as they provide more visibility and range. LED with projectors is something which is the best currently. Xenon and Laser lights are the ones which very high end cars use.
LED Projectors are now becoming popular in affordable cars like Ignis/Dzire and upcoming Swift. Soon LED (with/without projectors) will start becoming a feature every car's top model will have.
IMHO, Ciaz is the best value for money car you can buy. It has been a top seller for a long time now. Recently 2017 Honda city and Hyundai Verna have been updated and trying to move ahead. Similarly Ciaz will be receiving an update before mid next year and surely will be back to the top!
