For starters, I'd post this in the Forwards section -- you'd get more attention.
Secondly, give clarification as to what categories you're talking about -- all leagues are different and these guys might have differing values dependent on position (RW vs. LW) and what your league counts (+/-, points, goals vs. assists, etc.)
If you're talking pure points, I think I'd roll with Hall based on the #1 draft pick and perhaps biggest upside, although all three are looking to have solid potential.
Eberle and Skinner are performing better early, so if you'd be looking less into the long haul, and more into this year (or perhaps dealing them), then there's justification for grabbing them for that reason.
