I've been using Rex Domestique. Disappears pretty quickly in rain but the chain stays pretty clean and some lab tests say it's fast. Conveniently small bottle, that costs the same as other bigger bottles. For example last year I did TCR and then cleaned the chain with just a rag, lubed the chain and it stayed quiet and shifting was good for the whole PBP without lubing it again, as there was no rain. So basically, I like it because it's easy to keep the drivetrain clean.
