Hi Shawn,
Like others have mentioned, my experience with gaiters has been always with hiking. I haven't used them for hunting.
For hiking, the ones pictured above are some of the best I have ever used. They are heavy duty, they stay put at the boot, and stay put up top. Some of the "zip up the back" style I have had problems with the retention up top holding, or the zipper slipping, and them wanting to fall down. It seems if you have to tie them up top, they are more of a pain, but will stay put. I used a pair that had a string and cord lock, and the cord lock kept slipping. Annoyed the crap out of me.
One of the other things to consider with gaiters is your activity level. Goretex or no, if you are hiking a lot you generate more sweat faster than goretex can vent it. Every pair I have used has developed "condensation" on the inside. Still way better than what they are protecting you against.
For hiking, my reasons for gaiters have always been mud and snow. If you step in semi-deep snow, it will shove you pants up over your boots, then you get snow inside. Gaiters are great for not letting that happen. Next is mud. Pretty self explanatory there. They will save your pants for sure. They also help with abrasion. Most hiking pants are expensive, and if anything gets rubbed, kicked, or abraded, it is usually at the ankle. So, they do really help for that. Like others said, most are not designed to be quiet.
For hunting, I have used
Filson's Tin Cloth Chaps. But, I have only used them in upland bird hunting. For running through the briars and tangles, they are great! The waxed cloth also does an excellent job of keeping you dry. However, they are a bit high for most needs.
It is funny that you brought up this topic because I was actually planning on making my own. I like the tin cloth material, but want them like short hiking gaiters. So, that is what I was planning on making 
Good luck finding something that works for you.
