For what it's worth, I upgraded from a 622 to the hopper and needed to get the ota module to keep watching ota channels.
The only con I see is that the hopper's ota module does cause some picture pixilation fro time to time, but not often enough to be annoying so I consider it a minor issue. On the plus side, for some reason, the signal strength of marginal ota channels is much better with the ota module than with the 622.
