Tough Choice but I would say points actually its the stay credits that I'm interested in for elite status, UNLESS it is this time of the year and I have already reached my top level tiers and the stay credits don't really do much for me except put a few more points in the coffers.
I could find some nice properties using Marriott, Hilton or Starwood that would not hurt my firms image. But heck I'm with a gov't contractor so they expect anything that will give within Per Diem so almost anything looks good
