I have the 3. 54 gears and 6-speed as well as a PE Comp, so the giddyup is fine at this point- only the initial launch at stoplights is different. I will probably change to 4. 10 or 4. 56 gears eventually, but it's not too big a priority yet (lower priority than clutch, injectors and B1 turbo!). I never used to use 1st gear unless it was real steep or I needed to go real slow, so I use it more now... but not every time. I think my truck sits a little low in the rear, so I'll be adding another inch of height to the rear when I add the traction bars... just my personal opinion!
