Hybridization capture: Array-capture vs. in solution

If I wanted to utilize hybridization capture for capturing certain genomic regions, I could do it by utilizing complementary probes immobilized on an array or to use the probes in solution and then capture probes using biotin-streptavidin binding.

How do the two compare? Does in solution hybridization e.g. require more probes? What would I need to think about when making my choice?
