Without the OP adding any details regarding how many keepers you keep and positions, it's harder to evaluate the true worth of these players.
In an 8 team keeper, I'm guessing that you have to start 2 goalies a day/week. In this case goalies are more valuable as the yearly draft or FA pool is slim as each team will most-likely have at least 3.
But like I said earlier, the Stamkos/Vokoun side will most-likely be better this year and possibly next depending on where Vokoun signs.
With that being said, I am a firm believer that Giroux will hit 100 pts by the end of next season.
