Me, my personal vote would be for RSOS, but that's mostly a greedy vote
to improve latency (and because I think we're a ways from running into a
scale issue on our onion site).

What would be most beneficial to the network if a lot of non-hidden
onion sites start to appear (say, more mainstream news sites), some with
large traffic? I'm not sure if that would even be an issue, nor am I
sure if it would happen, but it's a thought I have as I continue to
share our onion site with my friends and counterparts. (My gut & basic
understanding of the proposals says RSOS.)

RSOS reduces the number of hops between the client and onion service from 6 to 4.

(With circuit cannibalisation, the hop counts can actually be as high as 8 or 6.)

So it is better for latency, and puts less load on the Tor network.

Rendezvous Handoff means that each Tor rendezvous goes through a Tor instance with a different set of guards.

This overloads particular relays less, and loads each Tor onion service instance less.

But this effect can be partially achieved with OnionBalance, or with Alec's "multiple onion services with the same key" failover arrangement. (Do you have a catchy name for this, Alec?)
