Just bought the Samsung S90F, but have been a fan of the Sony Bravia series for a while. The difference maker for me was that the Samsung has the Spectrum app already on it. No need for a cable box or Roku.
I used the site in the last thread about TVs (rtings.com?) and searched best TVs for watching sports. The top two choices were Samsungs. The Bravias have a setting for sports, motion-flow, that works very well.
