Although yes they are better quality, they are only 3A max rated. The controllers draw 3A at full tilt (on main beam) but only 1.5A on normal use (DRL) or <1A on night use.
So the only issue is the heat generated by running the controllers on main beam may be too much for the PSU to deal with (it has no heat sinks) which may ultimately lead to the PSU failing so keep an eye on that.
I do agree about the other PSU though, it is a bit crap but is well rated @ 80w (9A+). Above all, make sure you all use fuses (1.5A per controller or 3A in line to both) between the PSU and the controllers.
I have had 2 returned to me so far that on inspection are both due to the PSU spiking and blowing something on them.
