A much better place to ask this would be on the New York discussion board. It will get a lot more visibility there from people who can offer informed opinions.

 
Personally I don't use Eros and have never heard much good -- yes some find good providers but the majority of opinions I've seen see it very much as a YMMV site with limited quality control.

 
Assuming you are a newbie or first timer you are wise to avoid any providers you are not able to find some reviews available. When trying to make the decision don't just trust the reviews. Some will be false. Some will just be from people who have different preferences and desires for a session from you. If you find a reviewer has only one or two reviews (yes, I know my current handle only has a few but I've actually been on the site form over 10 years and have plenty of other reviews) then don't give those reviews much weight in your decisions. Look for reviewers that have many reviews over a year or more. Then you can PM them to ask any questions you might have to clarify just how well aligned your priorities and the reviewers priorities regarding a good session are.
