As you said, Airtel is the best in terms of PQ...
I haven't experienced VD2h, Reliance, or DishTV, but in the past 5 years, I used 3 dth services. Started with Airtel HD moved on to Sun Direct HD then Tatasky HD and again back to Airtel HD. I felt Airtel HD is superior in terms of PQ as well as AQ. Tatasky is good for only Value Added Services. I used it only for 2 months and switched back to Airtel. To my knowledge if you use Tatasky, you have to fine tune your TV settings to get better PQ whereas in Airtel, even with the factory settings you will get great PQ. Moreover, Airtel would be the leading the race on adding new HD channels in coming days.
Regarding packages, if you go for advanced rental pack, I would suggest for now opting for a mega or a magnum 3 month plan... if you go for yearly or 6 month plan, then you may have to pay more for every HD channel they add in future which would cost you more... so for now best would be monthly or a 3 month plan...
