We had this discussion on a flight the other day during a check. Common consensus was we would land. You are VMC, runway is clear, you are stabilised for approach. Why risk going around, taking up the missed approach procedure to enter a hold and then come back for another go when you have no idea of what traffic is around you. You are assuming ATC will automatically click into "comms failure mode" and coordinate everyone to stay clear of you. What if they are a bit slow off the mark? Maybe their radar is off air and they don't see you squawking 7600. Maybe they are busy, maybe thats why they forgot to clear you to land. Maybe they lost their comms as well? Its safe and there is a runway ahead of you and you have presumably been sequenced correctly for spacing on the final approach. Hence use your captains discretion, get it on the deck and worry about filling in the paperwork later.
