Sometimes/maybe. Due to the nature of how stuff down there is screwed together, the stabilizer bar has a 1:1 motion ratio with a MS design, meaning that one inch of vertical tire movement is translated into one inch of movement at the stabilizer bar, because the bar is linked to the strut itself. But with a wishbone suspension, the stabilizer bar is often connected to one of the wishbones, somewhere between the outer ball joint and the inner bushing. Let's say it's halfway out. This gives it a motion ratio of 2:1, meaning that for the end of the stabilizer bar to move up or down 1", the tire has to vertically travel 2". This reduces the leverage the stabilizer bar has on the tire, necessarily INCREASING its rate to compensate for that. A MS strut design can usually get away with a lighter stabilizer bar. The other side of that coin, though, is a wishbone setup usually offers more camber gain, which can compensate for body roll during cornering.

I think it can be, depending on what you like. I used to own a 2011 Camry and could compare it directly to the 2011 Fusions we have at work. Camry, of course, uses struts all around. The Fusions use wishbones/multi-link. Ride quality in terms of isolation was better in the Fusion, but isolation comes at a compromise of road feel, for which I preferred the Camry. MS designs tend to use fewer bushings, which can translate into more direct response. BMW and Porsche both use strut designs, and likely due to this.
The real take-away here, in my opinion, is that there are no absolutes in suspension design.
