I'm the same, I've never had a problem with Kryston hooklink materials giving way on me, although I always check and double check my knots after I failed to do so after landing a fish and the knot gave way. I had a combi rig, Amnesia to Merlin, and after landing a 20 on it, I cast it out and the combi join knot way. It was my fault, I didn't check after playing a strong fighting fish and cast straight out.
That means to me, after every fish, before every cast or on retrieve, check your mainline for damage in case you've fragged it, especially near the end tackle as run rings, lead clips stress, gravel and snags can take chunks and frag your line.
The most common cause for a breakage is a badly tied or wrong knot for the material or even sliding the knot down without lubricating it.(Do NOT use a blood knot with braids!)
My Kryston problem was that the coating on Jackal I found a bit weak and would split, ( coating only) when I did snug the Uni knot down properly even when it was salivated on.
As for braids coated and uncoated, with the exception of Jackal (for me personally) look no further than Kryston; Merlin, Silkworm, Mantis, Snakebite or Snakeskin etc will not let you down
