Recent facelifted sonet has many features in HTK plus compared venue S and also Kia and Hyundai are same company so on other aspects Both are same. I would say sonet, better you test drive both and decide
If you want pure sporty feel as an enthusiast you can go for i20 and if you want both sporty feel and as a family car you could go for venue. And i20 has good amount of ground clearance, it has never scratched in any potholes or speed bumps. So if you thinking about venue only for ground clearance you can go for i20 with no worries. Other than that it's your choice. You can better test drive both and decide. Or if you want more info,please tell your needs,I'll suggest ! Keep supporting ♥️
Based on your needs bro. Both are good on each aspects. And i have not driven fronx personally.If you're car enthusiast you can go for N line.N Line is good for both driving pleasure and comfort
