I have had the Pathway X2 for 2-3 years and love it. Two other advantages not mentioned in other comments to date:
1) Two different times I have been able to get my "home" locals when way out of market. Once on the western arc and once on the eastern arc.
2) Last Super Bowl we had my Pathway and a Tailgater side by side both tuned into the same station off the same arc feeding 2 different TV's at a large party. A rainstorm came through, the tailgater went to SD and then lost signal (rain fade) the Pathway kept HD throughout the rain storm and never dropped the signal.
