I had my gelding in a 1680D Dover Northwind... it got a hole in it (as well as broken hardware and torn piping). He now has a Rambo, but I got that at the tail-end of the season, so it remains to be seen how well it will hold up. I don't think it's so much him - I think his "friends" are unusually hard on his clothes.

I had a Saxon 1200D rain sheet that lasted forever. My horse lives in a giant field with about 20 other geldings and they all tend to play and rip each others blankets off. I was super happy with how long the Saxon lasted though and when it finally died it was only $60 to replace it. Makes me less upset than when he ripped through his $200 heavyweight.
Anything at the highest end of the denier range works for me. 1680+ is my choice. I've got a mare who takes great delight in ripping strips of blankets off, and so her pasturemates are now clothed in heavy duty blankets, which seem to deflect her teeth nicely. 1200D and below stand no chance against her shark-like tendencies. I haven't noticed a big difference between brands.

I have a Shire's turnout (can't remember the name, which ever has the 2000D). It is so far unbeatable.
I also have a shires turnout, but it's the heavyweight stormcheeta... my guy is turned out with absolute blanket destroyers and it's lasted for 2.5 years so far. All of his lighter turnouts are shredded from his turnout buddies so it doesn't seem worth it to get anything but a shires considering the price is better than the rambo and it's just a nice!
All of mine except the Rambo Wug have been destroyed by the pasture mates. They even managed to rip the front buckles off the amigo sheet I had on him several weeks ago. I think I'll try the Shires or Saxon next year!
FYI the higher the denier, the harder it is to tear apart. My horse that's crazy hard on blankets will be getting either a 1800 or 2000 denier blanket next year, despite the fact that we live in an only mildly cold climate (doesn't get under 30 normally).
My pony has a Baker heavy and a Baker sheet - she is more of a alpha so doesn't get picked on a lot, but those have both lasted at least two season, and probably more, as she came with them. I would buy another in a heartbeat.
The Pessoas I've dealt with have been junk. The Rambos seem to last pretty well, though, they'd probably be my second choice.
The Dover Polypropylene sheets (not sure what the "name" is) are awesome! They are the most indestructible sheet I've ever owned. Easy to clean, too. Also, if your horse does somehow destroy it, they are not super expensive and are frequently on sale for very low prices to get a replacement.
