Nothing is going to be unanimous.
However, people who ride Carbonda are quite consistently happy with them, but they're more on the gravel end of things.
Over the years velobuild has been improving their game a lot, doesnt seem to be the gamble it may have been before.
Lightcarbon generally has very good reputation, Yishun too. They are / were / still probably are the same group somehow, or at least related parties, and Yishun OEMs for big names (it's spelled out on their website).
SP Cycle / Tideace / Haideli are about the same price point as velobuild, it's a bit confusing because they do open mould frames and i think they're all related parties but i'm not sure, it gets confusing. Either way, they dont seem to be very popular here because few post about them, but i havent found anyone saying bad things. The R025-SL for eg looks like a VERY compelling bike (but is 30C only). I may have bought one had it taken 32C.
