Gentlemen, it seems that only handbags at dawn will settle this. So will you meet on the asphalt or the grass?
i've long been persuaded by the asphalt camp, but it is surprising how dominant training cultures can be in creating an [almost] entire nation of pilots who will choose one over the other without really paying much attention to why.
One colleague missed the field during a night auto in the sim, by a mile or two, and justified the landing foray into the blackness with the grass preference argument. Yeah right.
Asphalt will also likely give you more ground effect at the bottom in a marginal situation.
Landing on a big runway in a small helicopter (and without rad alt) can make judging the flare height difficult. I'd go for a taxiway or apron, as someone else mentioned.
