I would say neither. I would hold on to him as he has been very cold lately and he is known to produce in bunches. When Kesler returns, Vancouver should have 2 good lines, which in turn will give Garrison many even strenght scoring chances.
At the moment he is not worth much, but if you stick with him a while longer, I think he could bring you good numbers or at least some trade value.
