Drouin will likely hold more value than Eberle in cap leagues at the moment. Who the actual better option is longterm though is a coinflip IMO.
A lot depends on a team by team basis. If you're struggling to get down to the cap, Eberle+ for Drouin is likely a smart trade. If you have no cap issues and think you can contend this year, trading your Drouin for Eberle is probably not a bad idea either.
