Navi Mumbai vs Mumbai - which one is better for starting an office as well as living?

Hello all. So my company has asked me to start an office in India (till now I used to work as a consultant for them), and I am contemplating where to do so. Initially, I plan working from a co-working space until I get an office space.

I am thinking navi mumbai as cost of living seems reasonable and the area seems better planned than Mumbai. I also would like to minimize my commute, which seems impossible in Mumbai.

What are the pros and cons of living in Navi Mumbai?
