Rubik's Official Lube or Jig-A-Loo?

Ok, I ordered two DIY speed cube kits, one from Rubik's.com, and one from cube4you.com, with the one from Rubik's.com, I get a projectible silicone syringe, and at home, I have Jig-A-Loo. Now, what should I lubricate the cubes with? I used Jig-A-Loo plenty of times, and it's phenomonal, but, I have never used Rubik's.com lube, and I wanted to know what's better to use.
