[What Bike]: bajaj discover 150s vs Yamaha sz rr

Hello frnds,

I am planning to buy a bike under 70k in delhi. My requirements are:-

- good city bike with good power
- occasionally highway trips, bike should be able to run at speed of 80kph with ease
- mileage would be 45+
- driving experience should be very good if not best (don't want to compromise)

I have shortlisted following bikes:-

1. Bajaj discover 150s (did not like 150f)
2. Yamaha sz RR
3. Yamaha sz s(if budget does not allow)

Please share your views on above bikes. Personally I like sz RR but I have to pay 8000 more compare to discover 150s. Do you think its worth to pay that much more? Secondly people say bajaj bikes are not good for longer time. Do you think bajaj discover 150s is having better quality than past bajaj bikes.

I am really very confused. Guyz please help me, I want to buy bike soon.

Thanks in advance.
