From my
limited experience, it could be any of the things in the equation
Peer? - Are you using local card?
Cam config? or version?
dish related, could even be the cable (had similar issue due to this, but with cable and not sat)?
In my opinion, and unfortunately, its a process of eliminating components from your issue as much as you can... Although the other posters in this thread are more experienced/skilled hobbyists than myself, so are probably able to dismiss components id include in my 'investigation'.
EDIT - Ignore the peer comment, as its on FTA too...
Also to answer your original question, the term 'best' is subjective and what is best for one is not necessary for all or even any other.
What you mean by 'best' is, do you think any of the backups will alleviate/resolve your freezing issue
