I'm on Tiagra 4700 10s here so not the usual 11/12 speed groups which are more common around the forum (here in Brazil groups are really expensive so I'm still holding on the upgrade)
I usually rely on KMC X10 which I think offers a good cost-benefit, easy to find it for 20usd (or less) on aliexpress and last 7-8.000km or more depending on ride conditions
I've had one shimano 10s in the past, but I got it too cheap and think it was fake, before 6.000km it was already >0.7 wear...
it's easy to find cheap ones in Aliexpress too, but then I'm a bit concerned about the quality, and prefer to risk it on the KMC's - which I know there's a lot of fakes around, but even if the ones I got are fakes they at least lasted long enough
then right now I'm trying out the YBN, got a good value on a 10S one, it's about 2.000km and all good by now, but still a lot to ride before making my mind
