If you really want a good answer to your question, ask a big repair shop about their experiences..
I have been on the water kiting for 10 years and it all depends on how you treat your kites.
Most companies use Teijin ripstop and dacron and if you look at what kites are produced where it might shred som light aswell.
Placement of reinforments are also important but they dont count for anything if you dont take care of your kite.
In my eyes all the big brands are good going. If you dont take care of your pulleys they will eat the bridles no matter what logo is on the kite..
In my eyes Cabrinha, Ozone and slingshot are the ones that hold up the best.
I still have a 2007 Contra that has been to hell and back with no issues at all.. Will never sell it.
These days i got some smaller sized cabrinhas, a Fuel 13 and a Generator they work perfect for me without any issues but the cabrinhas has got more use that the c-kites and still look mint!
Aslong as you dont leave you kite in the sun, wind and sand all day it will hold up well.. Fly what makes you most happy. I dont see any brand with less issues then Cabrinha exept the strange thing that happened to your depower rope connection thats being replaced on warranty. (still dont understand what happened there cause that has never been an issue for me)
But, whats most important to me is a cool local shop that knows its kites and is in it for the passion, that helps out and make u feel welcome!
