I find myself along with Nadia to really love this Grace Community Church. The pastor is really into the word of God, and the bonus is, he follows the reformed line. I think having 3 consistent Bible study a week (Thursday study, Sunday School, Sunday Sermon) is unusually blessed. It's not common in U.S. In fact, it is probably not as common anywhere in the world today as it was back in John Calvin's time (multiple times everyday!).
Other churches have failed in various crucial ways. Though if I must, I would still hold that there is some hope in certain churches. Rev. Lin's CCCNY by Central Park is not really, but sort of Reformed, only if she tries to associate herself/the church with some famous reformed preachers, so a cheap kind of imitation. But nonetheless, because of the imitation of the right kind, I believe God is blessing them still. Rev. Murphy's Messiah's Reformed Fellowship seemed to be reformed and there are more delving into God's words than CCCNY, in fact, I find that most Chinese churches in America are less into the word of God and theology than the American churches, at first I would think it has to do with language, that Chinese churches leaders don't speak English well in America, but then I realized it maybe something more devastating, that they believed they have struggled enough and have finally immigrated into "heaven", so all work is done, there is no need to seek anymore. But Murphy's church do show some kind of factions and struggle between making themselves a private exclusive club (like that of the OPC - where if you are not a church member you cannot partake Holy Communion - though not enforced) and evangelism. But they were quick to kick people out who's not their members, so after twice being kicked out of their online google group, I gave up trying to get back in, all I wanted was to make sure that they don't cancel the Bible Study when I sacrifice my time and effort just to attend, but I guess joining the tribe is more important for them. The other crucial thing is Murphy's preaching one time, when he tried to justify certain lies, but I assume he was going through something, given his character, not surprising. Overall, I would still recommend CCCNY or Messiah's Reformed Fellowship in New York City. These are the two only ones I can trust doing God's bidding or close to it. So if they are bad, then the image of New York Church is not so great. There are other churches note mentioning, but they are not reformed, just into evangelizing, which is foundational, so if one doesn't like CCCNY, one could try Flushing's Faith Bible Church, but be aware of the poor theology practiced there. As for Redeemer, since Tim Keller stepped down, I don't know how to rate it, very unreliable, even with Michael Keller, the son, leading the Lincoln Center branch. When pastors come and go so often, something fishy is going on. The messages in the sermons were not impressive either. By impressive, I mean displaying the living word of God. And in NJ, we sort of gave up Grace OPC in Westfield, seeing that they held too tightly to fundamentalist ideals (proclaiming virtual service is unbiblical) during Covid-19. The pastor kept saying "I love you" in email format but two families have declared strongly against it. I don't mind revisiting them, but now that we've found a slightly further (30 mins) Grace PCA in Bridgewater, we are going to stick to this, for I choose God's word over any formality or flattery or human care, which were made idols against God by many of these churches.
