I would suggest getting either the S2 or the Note.
I would also suggest waiting for the launch of HTC One S if you can wait.
Sony Xperia S is apparently a great phone. Not officially launched I think. Grey market price is around 32K I heard. I hear stories about anomaly in display colors and poor camera shots because of excessive compression by the processor. Check the reviews and decide on this one. I was considering this one before I switch my focus on
One X.
Stay away from RAZR because of the display and of course
Motorola branding.
Galaxy Nexus is also a very good option. 26K in grey market I heard. Get it over S2/Note if camera is not a priority.
If you can wait, wait for the launch of S3 in the Indian market. That should result in HTC and Sony devices getting significant price cuts.

HTC Desire and Galaxy S. Galaxy S is of course the superior phone but HTC Desire is a better built device. Decision is for yours to make!
Galaxy S is getting a software update from
Samsung. It's not ICS but it is still better than what HTC Desire would have today from the company.
