VIPRE + Comodo Firewall?

I was thinking about purchasing VIPRE Antivirus Premium which contains a Firewall (Sunbelt Personal Firewall).
However, from what I have read, Comodo is a better Firewall. Thus, I would instead install VIPRE Anitvirus + Comodo Firewall.

  1. Does anyone know if there could be any conflicts?

  2. According to this table:
    there are some features that are lost when going from Antivirus Premium to Antivirus.
    Would those missing features be covered by Comodo Firewall?
