Theologically, Catholics and Baptists are rather more in agreement than Catholics and Presbyterians but, in my town at least, Presbyterians seem to get along socially with Catholics much more amiably than Baptists do but Baptists more readily become Catholic than Presbyterians do- the largest Catholic parish in the area is composed in large part of converted Baptists.
That's been my experience too, at least with non-creedal Baptists. But when you toss in something like the 1689 "Baptist Confession of Faith" into the mix, that tendency to convert drops off.
