No sitting on the fence for me.
I would go for VantheMan as preference.
Both of them need bungee ropes to keep them back in their net. They are both guilty of that. Also, they both tend to try to play the puck too much and too often.
However, Van tends to have better position and comes across as more mature.
Sammy is more athletic, but also more erratic.
It's a fine line, but I have more faith when VantheMan is in net, than I do when Sammy is in.
