I prefer the original shifter, but it's the OPer's car and he should do whatever floats his boat. I'd say it's definitely worth keeping the original around in case of a resale, then the truck can be advertised as having a "like new" shifter!
Want to talk about frivolous upgrades, I have an STi oil cap on my FXT. I was buying a thicker rear sway bar and wanted to add on something to get free shipping, saw the fancy cap and thought about how nasty the plastic yellow oil cap on my car looked. The STi cap actually less practical than the OEM piece as it gets really hot and is hard to grip in general, but it sure looks cool in a completely hidden to the public kind of way.
