Not so sure of that one
Hi Raoul
As much as we like liquid water there's so much about Titan we don't yet know. If a sub-surface ocean and cryovulcanism are confirmed on both I would wager that the atmosphere on Titan will make missions easier in so many ways that it'll be the preferred choice. If Enceladus' warm patch is some kind of warm ice diapirism and the sub-surface ocean vanishes with gravity studies then Titan wins hands down.
