Which is the better investment?

I'm currently trying to figure out which of the following stocks would be a better investment, and thought I would ask the community as part of my due diligence. The stocks I am considering are STWD and NLY. I was wondering which othe two would be the better buy for the long run. From what I can tell, NLY has the better divident payout, but has been declining a bit over the years while STWD has a pretty steady dividend. Any advice would be much appreciated.
