@silverpill@mitra.social I an in depth comparison in this 3 part series: ipns://hypha.coop/dripline/p2p-primer-part-1/

The tl;dr is hypercore is way faster and more reliable for getting past NAT. Orders of magnitude faster updates. Only has a JS implementation sadly and no official specs. The team working on it is doing some crypto thing with bitfinex but that's not part of the p2p protocol itself. @agregore and distributed.press supports both if you wanna mess around with them.
