It's probably a toss up. Just a tid bit, I typically like to " trade into a goalie" rather than own prospect goalies. I'd load up on an extra player or two ( F, or D) and down the line when I see a prospect goalie start to materialize then pounce on a deal before his value goes insane. I've been burned to many times in the past to " sit" on a prospect goalie. Sure, both these goalies " should" be solid NHL'rs but I can find 20 other prospects that will have more value on a team and you can do something with before I plug in a prospect goalie and " hope"....
BUT to answer your question, I'd go with ED and side with Subban, I think he can be traded and fetch a solid return.
