Developer choice always makes a difference, especially in terms of final image color. MG Cooltone has excellent highlight rendition as long as your film itself does, significantly better than MG4, for example, and comparable to MG Classic in this respect. MGWT is quite different from either, with a much bolder DMax. I prefer to develop MG Cooltone in amidol, then gold tone it rather than selenium, because that gives me consistent silvery cold tones. If I want a wanted something other than "cool", why buy Cooltone to begin with? It's one of the very few papers still on the market that does this well. Conventional developers risk a bit of that greenish Dektol look with it. By comparison, MGWT in a warm developer like 130 followed by gold toning will indeed give you deep blue-black shadows, but not cool highlights! So it is a wonderful paper to accentuate this tendency to split tone using supplementary toners like sulfide. Nothing will make MGWT cool overall.
