My favorite saddle was my white perforated Turbo. It's still on my mountain bike despite not being a mtb saddle. Frankly it's probably only the second most comfortable, after my Selle Italia Expedia on my street-track despite being a mtb saddle. It's a close tie, I really like them both and I only put the Turbo into second spot because it's in pretty rough shape. Far and away the least comfortable is my rain bike saddle, a Selle San Marco Concor Supercorsa. It's so freakin hard, but it's old skool panache, so whatcha gonna do?
