I guess that would be subjective. I haven't found any quality issues, but I really don't have anything to compare it to. My FT radial motors certainly look nicer. Both the FT and TOTS ESCs seem to do their jobs. I have had 2 FT 5 gram servos strip and one TOTS 9 gram(not metal) strip.
Keep in mind, this over 30-40 flights, all short and all ending in crashes of some form.
I'm not the most accomplished pilot.
