We are adding another Citation VII to our small "fleet" and the few airframes we have it narrowed down to have the Honeywell boxes installed in them. Our other two 650's have Universal UNS boxes and our crews are familiar with the Universal's only

Are the Honeywell's that much better than the UNS boxes that we should keep them? We would upgrade them with WAAS if we keep them and as well would do the same and install WAAS Universal boxes. Anyone with experience in both??
