I'm assuming you're aware that the Zenith is both an OTA and DirecTV tuner and the Samsung is OTA only. With that said, I found reception for OTA to be quite similar in both as was picture quality. The Zenith is probably a better buy since you're getting both the satellite tuner and the OTA tuner. However, if you're after the ability to RECORD OTA HD, then the Samsung with its firewire output is your only solution (assuming you have an HD recorder!).
