You're comparing two rather different lubricants. I use Militec-1 on my balisongs and push-button autos, but it's too thick to use on my OTF autos, which are rather touchy when it comes to lube. Reccomended for those is Rem-oil, but I find Tuf-Glide works very well. So I'd say that you should choose the right one for your particular application. Either should work well for most. Militec-1 is thicker, but smoother, which works great for balisongs and high-tolerance pivots like on Sebenzas. Tuf-Glide is much thinner, which might give more speed, but less of the sexy-smoothness Militec-1 gives..
At the very least, email Militec for the free sample. I got mine nearly a year ago, and despite the apparent small size of the bottle, and the number of knives I use it on, it's still got plenty left. A 4oz bottle (like the Sniper pack) should last a lifetime or 2. i bought a .5oz needle-tip bottle of Tuf-glide, plus an 8oz bottle for refils 4-5 months ago, and I'm only 1/4-1/3 the way through the .5oz one. A little goes a long way, so don't worry about the aparent high cost.
For protecting, I use a Tuf-Cloth, which is basically a cloth soaked in Tuf-Glide. I prefer this over Militec, mostly because it's easier to wipe clean in case I have to use the knife on food.
