We actually quite like DOQ and DOH3, both of which use QUIC.

All modern Apple systems use QUIC. For instance if given 9.9.9.9 via DHCP they will automatically upgrade to encryption via DDR, then then upgrade to DOH3 with no intervention by the end user. We find that encryption load is lower with QUIC-based transports, but we need to really get a formal research paper together on that "in our spare time."

Faster? Probably, but is it measurably "better" remains a question for others to answer. Due to parallelism in most query sets, minor wins with DNS latency matter less than you might think.
