Should i take home loan from a bank the builder is suggesting?

I am planning to buy a flat on bank loan. I’ve checked with various banks about my eligibility and it’s fine.Builder in whose building i’ll buy flat, is insisting that i take loan from a particular bank which has already approved his project. He says it will cut hassles for him and loan will get processed faster. Do you think it’s fine to go with the bank builder is suggesting? Or should i go with different bank as it will again check all the legal docs of building?
