Additionally, I'm interested in knowing which crypto exchanges you find most reliable and why.
As always in Binance and other crypto exchanges that are popular. Mostly during the listings and that's how you make of the hype that Binance does for listing a new project there. The trend is still fresh but it's not always a good day that a listing is followed by pumping because there were times that it's mostly dump. This is applicable if you're an active trader and don't plan to hold those tokens and coins for long term.
Do they offer any unique features or token listings that set them apart?
There's nothing unique to it or if there is, it's about the community that supports them and takes advantage of the listing as I've said.
