To try and contribute to OP's question - I have no personal experience with OTTE but they have a good reputation for solid gear and feature-wise, those gaiters do look nice.
I personally use a pair of issued British MTP gaiters - solidly constructed but definitely "heavy" in comparison to many others. They also use laces where the OTTE (and others) use rubber bands underfoot.

He didn't ask about footwear, my man. He asked a question about a specific set of gaiters from a specific manufacturer.
Never mind that suggesting taping/bagging your feet is somehow better than gaiters for marching through brush, scree, etc.
