I am no specialist in Hindu philosophy but I'm not impressed with the philosophy taught by ISKCON. Yes, Achintya Bheda Abheda is a Hindu philosophy but in practice, Krishna is the Only Big God and you're the small soul and effectively, the emphasis on that not so far away from an Abrahamitic concept of God and soul.
I attend ISKCON Sunday feasts because I think "flawed" krishna-katha is still better than no krishna-katha. However, most of the time they don't speak about philosophy but get tangled in the stories of Hinduism, considering them as factual events that actually happened. In my eyes, this is also not so far away from the Christian concepts I'm familiar with. Christians in general have to believe in and confess (at least) the core stories of the Bible as actual events.
Many Indians in the ISKCON temples of the west have the exact same attitude, especially when there are no other temples to go to. That's why the ISKCON temple demographic has changed dramatically. When driving across the country, I'll stop at one maybe.
