I have never been to Moscow but live in NY, what are you trying to do in your trip here, establish business opportunities or take in culture and game? Obviously in the summer in NY you have endless opportunities to go to free concerts, movies and events in parks. There are many food festivals for instance which are a great place to take dates or meet people.
Before coming to NY I would highly recommend you read Time Out NY fora quick guide to interesting events throughout the city.

NY has many materialistic women and many who are not. NY is completely what you make of it. There are many cute girls who are cashiers and waitresses who do not expect anything material out of you. If you treat them to a drink that will be fine by them since they are broke. Of course there are also many girls living in expensive places they can not afford whose entire life revolves around milking men for money to keep up their expensive charade.
Obviously NY is full of University students from all over the place. Tons of museums, tons of art shows...
Moscow seems to be good because you are getting a particular type of girl there. You want a slavic beauty and thats what you get. NY is quite the opposite in that there is no one type of girl that exemplifies NY, and the pull here is probably the diversity. There is NY born and bred diversity and imports as well. You can go up to Washington Heights and meet Dominican chicks, can go to Chinatown and try to pull girls from bubble tea shops, go to brooklyn and meet European tourists gawking at hipster freaks. Spoiled rich girls and starving artists, classicly preppy girls in Murray Hill, bad bitches uptown, art students downtown. Tourists everywhere. Any language you like. I assume you speak some Russia and certainly you will find some slavic beauties here too if you care for that.
