In my opinion segwit is not losing yet. In the long run though there's a high probability that bitcoin unlimited will lose since right now it got many flaws but btc will go up in price even if none of these two is implemented. I really do hope that block size problems be resolved soon, I want to see bitcoin again having fast transactions just like the old days where the block confirmations are fast and transactions are settled within less than 30mins.
No one is winning right now, and bitcoin is losing.
The only one who profits from the current stalemate is altcoins.
Even if you think BU has too many bugs, then EC is still a good idea, and you can run Core with EC or Classic with EC, it doesn't matter, as long as the blocksize debate is resolved.
