Having roughly similar hours in each, I have a strong personal preference for the PA28, except when trying to get into a very short field.
The "more stable" feeling is almost certainly down to the higher wing loading of the PA28. The equation for gust response of an aeroplane is that the response is proportional to speedē/wing loading. So a highly loaded wing, which comparatively the PA28 has, will be much less disturbed in any turbulence.
There's an aesthetic point over high .v. low wing - depends whether you prefer to see what's above you or what's below, both rarely seems an option. But, it does feel less claustrophobic with the wing below - to me anyway.
