Advice on home loan

Hi

I have booked a newly launched property from a grade A builder. I am planning to take a home loan of around 1 CR for the same, the builder from whom I am buying the property is strongly advising to apply through their contact person (who is a Direct sourcing agent) who has tie ups with multiple banks like hdfc , SBI, axis etc. The builder is saying that the person will help get the loan amount disbursed on time and help with documentation better. That person is recommending SBI. I also connected with a hdfc home loan department person and he is suggesting I should go through him.

Can someone please suggest whom I should go ahead with? Also which bank is better and why? Also the expected interest rates and other charges?

My cibil score is around 755. I am the first time buyer and hence unknown in this area

Any help will be much appreciated
