Feedback on Costar vs Crexi vs Property Shark for retail leasing brokerage in the NYC market
I am a retail leasing broker in NYC and my background has always been at big shops with full scale research departments. I recently launched my own small shop with a partner and CoStar has been unpleasant at points. We are looking at CoStar vs Crexi vs Property Shark but are open to other services if they are worthwhile. We mostly use CoStar to search property listings for tenant rep, but are making a big push for LL work this year and want high quality real owner contact information. Property Shark also used to have a map layer that showed the current retail tenants in the ground floor spaces but that no longer exists. Here is what I am looking to know:

1. What is the quality and how thorough is the "real owner" data on each?
2. Is there any real value from the comps published in NYC?
3. Can we go without CoStar and still have most of the listing data?
4. What is the value for the dollar?
5. Any reasons to love/hate the interface?
6. Anything even remotely like the retail store map layer Prop Shark had anywhere?
7. Any other relevant features I am not considering? Other competitors?

I am grateful for your help.
