Anyone tried Lego technic, as well CaDa and Mattel Bricks?

Wondering how’s the quality of the other 2 brands. I have abut 15 technic sets. Using Lego sets to set my standard/expectation. And just finished my first Mattel Bricks set (300SL) and I would say the bricks quality is lower than Lego. The brick pieces are lighter (in a bad way that the wall feels thinner) and the pins fitting is not as good. I’m looking into some CaDa set - mainly the AMG one and AMG GT - wondering if anyone has experience with them can share how’s the quality ? ...
