What to Choose ?

40 ggpa as it's close to your town. You will save a lot of time travelling traffic and terrible work culture. Also financial above 50 you will have to bear another 10% surcharge as tax.

So it will be almost matter of peanuts when it comes down to in hand salary between Ggn and BLR expenses overall.

25 is a lot. But you are also 28. If you don't have any plans or gf then just move.

Always check what will be your inhand salary. The more they are offering means you have to pay more tax.
