What Your Preference? - Cross or Parker?

Honestly, I've always been a fan of Cross ink pens. I have one on my desk right now that I've owned for 6 or 7 years. I've temporarily lost it several times, but it always comes back.

But for my recent graduation, a good friend gave me a really nice Parker ink pen, engraved with my name and everything. It's too cool to not use. But I don't think I'll carry it much, since I definitely don't want to lose it.

But now is when I ask you guys about your pen pleasure. Cross? Parker? Bic? What do you think?
