Without any doubt go for Anand Vihar!
In Anand Vihar, all batches go through with the same curriculum. The best teachers include Shobhit Bhaiyya and Alok Bhaiyya. They are really great and if you get the chance to study from there, it is really an honour.
If you really want Pitampura then you can give exam once again. The main problem is in Pitampura there is one batch of droppers and they are taught by the founders themselves.
Also, consider the distance between your home and coaching. You shouldn't be travelling more than 1 hour or 1: 30-hour max (total I'm telling)
