>>11319314There's no small amount of subjectivity, some of us will be more tolerant of minor issues than others. Personally I've had good and bad experiences with most brands, but generally they come in pretty close to the Lego benchmark. Clear exceptions are Best-Lock (which has never been a good experience for me), Cobi (which has surpassed Lego in key areas) and old Enlighten (comparable to pre-Halo Mega Bloks, probably worse).
Kazi comes in a little bit below the likes of Sluban or QuanGuan for me but I've also quite enjoyed collecting their Military Power series.
