Electro-mechanical switching is prone to arcing, and this can lead to radio-frequency interference (RFI). Thyristor control eliminates this effect. In applications such as speed controllers for d.c. motors, it makes for smoother and better control than rotary switches using resistors. Overall, it is much more efficient in such situations. I can think of no disadvantages with modern semiconductor technology.

One of the advantages of a thyristor is it's size and that you can fire it with smaller current to trigger accormodating lager ones to pass through, simple english explanation.

much faster switching, no mechanical components.
switching can occur 10000 time a second reather that 10 times a second and enabes dimming and 0 volt switching . back emf can cause problems but correct circuit design make it ok.
