I use linkglyde chains on all my 11 speed bikes. LG500 chain is cheap. A bit stronger than other Shimano 11 speed chains. On our Etandem we started in 2000 with black and gold wippermann connex chains. I like the reusable quick link. Those chaisn did not rust. Bu ass well the 9* speed chaisn used for the timing chain ass the 11 speed chains for the rear chain did break very often. The links came loose of the pins and we even broke some sram 9 speed quick links.The chains wore also very fast, just like the xt cassette : 2 chains 3000km one cassette. I tried HG93 chaisn for the timing chain and they rarely break. oiled chains that break offroad : omg. Some chains I was using had over six quick links because the chain s did break a lot.
Everuthing changed when starting to use linkglyde 500 chains that I hotwaxed with silca wax. I use 3 chains per cassette. I wax again after every wet ride or after 200 to 400km depending the terrain.Chains on the tandem have over 2000km per chain, deore cassette has 6000 km. Far away of the 0.5 mark that means chain is over. 3 chains +one cassette costed 90 EUR. I think they wil last 10000km for the set. I don't ride offroad when there's only deep mùud like the last weeks in december in Europe. But 1/3 of our rides are in wet conditions. So far I did not break one link glyde chain. After almost every ride I clean the chain very quickly : dry dust : microfibre cloth with denatured alcohol wrapped around the chain and do a few turns with the carnks on it; not too muddy :same; wet and muddy: clean the chain in boiling water, dry and rewax or take the chain of and keep her in a microfibre cloth until I can+wax clean the chain. Linkglyde chains (just like deore/105 and slx chains) rust faster than XT+XTR but they hold wax better than XT+XTR.
Ther is one caveat : I also use linkglyde on my solo MTB where id od a lot more distance: there I noticed that when the chain starts wearing, it goes fast (not linear) so then you best check your chain length every time u change the chain.But I got around 9000km out of one casette and three chains. Solo I ride more challenging terrain ans shift a lot more. On this solo bike I changed recently shiftres+cassette to linkglide. Also waxed but with food wax this time. A lot cheaper than Silca. Have to wax more often. But only around 1500 kml done in this setup, so cannnot say much about wearing rate.
I use Yaban and connex reusable quick links.Alsoe the shimao and Sram 11 speed links i use more than one time.
