I've seen some sing Liquid's praises, and Blockstream's overall (aside from maybe the Jade wallet, fuck them).

To give a better reason, I feel drivechains have the ability to further expedite and optimize transactions by freeing up the mempool, but it needs to be implemented properly.

Giving more control to the miners is a double edged sword; I feel a hybrid approach that incentivizes both miner power, and the consensus Bitcoin is known for, would be ideal. Don't know if such an approach would require yet another hard fork though.
