Well as far as longevity goes, the FCC requires cable companies to carry local broadcast channels unencrypted and unchanged. So those won't be going away. I assume that any channels you currently get through your 6200 are unencrypted, so the difference would only be the source as far as I can tell. If you are using an IR blaster and an analog output to get the encrypted channels off of the 6200 then points for the 6200. If you are interested in getting broadcast ATSC OTA signals at some point then points for the HDHomerun. Basically I think you will get the same selection of digital channels with either the 6200 or the HDHomerun.
