Tayda switches have always worked just fine and held up quite well for me. To me though, their switches have always been a lot quieter and just "lighter" sounding. Like, when you press the switch, it feels like it takes less force to activate and it almost feels as though there's just "less". I don't know if that really makes sense - to me BLMS and others just seem to feel more substantial, more weighty, more durable, whatever - but, like I said - I haven't ever had any issues with Tayda switches either, so I don't know that they really matter.
In short, BLMS and etc switches sound and "feel" more sturdy to me, but Tayda's have never given me any trouble
