In the 80's, each winter for several years, I compared a quarter wave vert on top band, gnd mounted, with over a hundred radials buried. The other was the same antenna, only raised feedpoint, single counterpoise. Regularly noticed stronger reports on the much simpler antenna. Also noticed, if the counterpoise was angled downward a touch, the feed point would approach 50 ohms. Good enough for me, and plan to try it again soon.
