According the the Akashi page, any torpedo that's maxed gets an extra 3.7 to torpedo while a +6 is 2.9 to torpedo.

And as a guy with 2x 53cm bow, 2x FaT, 4x maxed Quad oxy, 2x maxed Quint, and Maxed Proto Sextuple. For subs, aside from always using their torps I rarely use my quads on them for maps when I need that extra power but I do occasionally use my quints and sextuple mount.

For surface ships though I really can't say what you prefer but do consider that quints provide that +1 accuracy where quads dont.
