I would consider to land for the reasons stated by Barbie.
Read your lost coms procedure: eventually you land at an airport, without specific clearance. So why add risk by going around, back into IMC, flying through busy airspace without radio, disrupting the whole ATC system, just to follow the lost comms procedure which ends in an uncleared landing anyway? Whilst you see a perfectly clear runway ahead of you?
You are the PIC, you look outside, you decide.
