Platinum Preppy lol. Just a good knock about pen. Currently I use my other pens pretty interchangeably for letter writing and journalling. But the Preppy takes the cake for the most general use. Second to that would be my Pelikan Twist since it's also a nice knockabout pen and with a medium nib (Preppy is F), I use it when I want to jot something down that really stands out with thicker lines.
