I like both locks, I own and use knives with both. I’m not sure however how easy they are to compare, they seem very different in most ways and share mostly superficial similarities.
I have had an omega spring fail but…well the knife had been filled…a lot, on top of that it had been used in tough conditions. Getting it fixed was simply a matter if sending it back to BM for warranty work, a little inconvenient but I’ve worn out two liner lock knives and one frame lock knives in similar fashion, when they finally went there really wasn’t anything they could do to fix it.
To the people who feel that the polymer cage looks/feels cheap remember that its there for a reason and is the reason why the CBBL is self lubricating and relatively low friction.
