So, in summary, none of the above come even close to Bitcointalk neither in terms of content nor, very likely, prestige and history of its members.
Definitely. The only forums I've really used for a while is bitcointalk.org and bitcoin.com(in the past, when I thought bitcoin.com was the "official" bitcoin website 🤦♂️). At the moment, I'm just with bitcointalk, r/bitcoin, and r/cryptocurrency(if you actually consider subreddits as "forums").
The Bitcoin Pub forum also looks decent though.
