It depends on what kind of lifestyle you want, what you can afford, and what your visa situation is. Here is some info that should help:
Singapore: Pay out the ass for everything but cool as hell and a strategic location if you can afford it without working yourself to death while following all the laws.
Dubai: You will likely have very little interaction with local Arab Muslim people and will mostly deal with overseas workers from the Indian subcontinent, Malay island countries (Indonesia, Malaysia, and the Philippines), and other foreign countries. So you should be more concerned with what your relationship with those people will be like than what you relationship with the local Arabs will be like as the only ones you will generally interact with on a regular basis will be your bosses. Also great and strategically located if you can afford it.
India: Extremely large and regionally diverse country with so much to see and explore that it could very well take you a lifetime to come close to seeing it all but you will never really see it all because a place will change as soon as you leave and will become a new place you have not seen yet. Also a lot of ethnic diversity with darker Tamil people in the south, lighter people in the north, tribal SEA people in the far east near Burma, Tibetans in Darjeeling, etc. Great place if you are into all that and want to live on the cheap and a very conservative culture so you could marry a traditional girl and move to some less crowded and molesty area to raise a family in the future if you should decide to do that.
London: Stabbings, acid attacks, and no realistic hope for a brighter future (especially if you do not like Islam as you have stated). Upside:
NYC: Statistically safer than London somehow. You will never (or at least should never) try to start a family in NYC. So only go there as a temporary thing or once you have decided that you never want a family or a serious LTR. If you never want a family or serious LTR and are into the player lifestyle for the long haul, it can be great. Also, you are still in the US and will have to deal with everything that comes with that (and everything that will come in the future).
Miami: Miami is cool if you like Latin people and Spanish but it is not a very big city, the region is completely flat, and there is nothing else of significant interest nearby (within 2-3 hours driving) so you could easily get bored after a year or two. Also, there are hurricanes and you are still in the US and will have to deal with everything that comes with that (and everything that will come in the future).
Some possible alternatives to consider:
Johor Bahru, Malaysia or Batam, Indonesia: Live essentially in a suburb of Singapore for much cheaper and with more relaxed laws.
Muscat, Oman: Like a cooler and more historically interesting version of Dubai and the only country in the world where Ibadi Islam is the dominant religion. Ibadi Islam is probably the most relaxed and tolerant form of Islam other than the Ahmadiyya (if you consider them Muslim which most Muslims don't) and, because of this, Oman even has Hindu temples and churches (something you will never see in other Arab Muslim countries).
Maldives: Get in and experience this beautiful island country before it's gone. With the highest divorce rate in the world, the Maldivian people are probably at least a little promiscuous. Also, polygamy is legal so you could get into that and just rotate your wives by divorcing them once they start getting close to the wall.
Moscow: All the cool stuff about London and similar in size without the feminism or Pakistani grooming gangs.
Las Vegas: All the fun of NYC without the freezing winters and the astronomical price tag. Unlike NYC, you will probably need a car but it's probably worth it.
Tampa, Florida: Cool and coastal like Miami but more relaxed and probably cheaper. Ranked as being one of the best cities to live in the US and, having been there many times myself, I can say that, if you must stay in the US, you could certainly do worse than Tampa.
