Smash Lord
You're right about the other smashes but our previous up smash actually had a lot of utility. Its main benefit was its speed--it came out somewhat quickly and had very little endlag, allowing it to move into ftilt, for example.And the old up kick u-smash doesn't even hold a candle to the new one, but I guess which moves were more fun is subjective.
Neither up smash is better, they're both useful with different utilities. I'd love for old up smash to replace current up tilt.
On the topic of buffing Dorf, making up B untechable and thereby removing rockcrocking would make him significantly better in competitive while having no affect at all on casual players, since casual players don't tech. IMO it's the best and simplest way to meet both quotas, it just comes down to whether the devs realize it.
