What are the top-rated shotcrete machines for large-scale construction projects?

Man our crew took on this massive tunnel job recently and its been an absolute mess. Our old rig literally died on day two and blasted wet mix all over the foremans truck. Total disaster. Lemme tell you we desperately need an upgrade before someone gets fired. So I gotta ask guys What are the top rated shotcrete machines for large scale construction projects?

I was sitting in my truck doomscrolling on my phone to find replacements. Ended up deep in the Alibaba app just seeing what heavy gear they even have. Ngl I was pretty surprised. The listings actually had insane detail and these videos of machines just spraying perfectly smooth with zero clogs. Made me think finding a decent beast of a machine is definitely possible.

But honestly Im just super lost looking at all the specs right now. Like is wet mix gonna be way better than dry mix for a job this big? And do those giant trailer piston pumps actually deliver real volume or will they just choke up constantly? Please give me some solid recommendations cause Im totally clueless.
