The idea about "tagging as anycast" is not to make other networks prioritize these (and prioritize in which way, anyhow?) but to give them the chance to do informed decisions on hot/cold-potato routing, which might look different for anycast and for non-anycast prefixes - or, when faced with "what looks like funny routing", to do better informing debugging.
What would be your preference about how your upstreams handles your packets? Hot or cold potatoe routing?
That really depends on where I am located. If I'm in just one place, but do connect in a remote location, I would prefer the local-to-me ("cold potato" for them), because that would reduce my backhaul costs. If I have an anycast setup, I'd have servers in all the places where our networks meet, so "hot potato, give it to me wherever you can", because that's the point of anycast.
