Given 50PSI pressures, it's definitely the way to go.

I have gotten comparable results with impingement as micro-channels would with atleast 3 PSI. Atleast with 1mm channels anyways. I have no idea how true micro-channels(as the name applies) would do. But I have to stop and think if I'm effecting another block in the cooling loop that might be there.
Do I think impingement can out do a micro-channel block with just 3PSI? No I don't. I believe it would be an even call. 50 PSI? Sure but it isn't practical.

I've always been curious if the rapid pulsing effect of the flow would create favorable turbulence by rapidly increasing and decreasing the jet impingement radius, and the pumps can typically push up to 600PSI or so. It'd be a "cheapish", if rather noisy, way to conduct the experiment, and when you're done with it, you get to clean your car too.

Never considered that. Some hefty hose clamps and high pressure hose would be in order. LOL I did hook up my garden hose to my block without impingement and gave it try. The ground water always stays roughly 23C here. Just 3C under what my water temp is now. I was amazed how well it did. Now you got me wanting to try it again with impingement. I enjoy your insight Cathar! You got me to realize a few points I didn't think about.
