I don't know. I've just heard it from riders who are not by any means idiots. Those asserting this spoke of better materials but, as the Turkey Vulture man said to me earlier, they may have been comparing dura ace 10 sp apples to $15 SRAM oranges.
As for masterlinks, let me assert here and now and forevermore that a 8 speed SRAM link works fine in a (well, this was a circa 2003 model) Connex chain -- if you are running a single rear cog. FWIW, said Connex 10 sp chain came with its own reusable masterlink, which I used on my '03 in its first incarnation as a 1X10 gofast. Moving on to chain life: I get 2000 miles pretty consistently to 75% wear on the Park tool with my $15 (6-8 years ago; now probably $20) SRAM chains, keeping them waxed or, later, lubed with reputable dry lube every 200 miles or so. Dust, very infrequent downpours, some dirt, mostly pavement, heavy torque up hills. Does anyone have any idea why this should be so? It has been so long since I measured wear rate on a chain used on a derailleur system -- I tend to modify and replace before wear -- that I don't know what their life would be.
