I've found the Rambo fly sheet to be pretty good quality and it last better than another brand I bought.
I've also found that whatever fly sheet you buy, it is not 100% effective. Especially the tiny flies that cause 'sweet itch' seem to get in anyways.
The other problem is the really big flies that bite through. We find that the soft meshs work great with the horse flies but we have another fly (don't know the name) which is really big and nasty and goes through them (just the light mesk, not the solid ones.
I think there are some good tips here: http://wowhorses.com/horse-fly-sheet.html
Sorry, but haven't tried the brands you posted (yet).
