Bitcoin "Classic"! What a stupid name. Logically there's nothing really classic about it. They should have spent a little more time thinking up a proper name at least.
It's called Classic because it is was inspired by Satoshi's scaling solution. And is in keeping with his vision for a Peer-to-Peer Electronic
Cash System.
Bitcoin classic is BIP 102

Both are good.... but Classic isn't that exciting now that they decided to remove 2-4 + segwit as an option.
Regarding your dev numbers, most of those guys have no financial gain with blockstream, so will follow where the action is.
And again, your figure for Classic is wrong. But if that's a figure that helps you sleep at night, then go for it.
