I have both a MP40QD and a gyre 130. The MP produces a better flow pattern in a wide and strong cone with almost even flow through out while the gyre produces a blade of flow that cuts across the top of my tank. The control of the mp is way superior as well with reef crest/lagoon mode changing it up all day.
gyre or powerheads?

So what you are saying is that the gyre produces flow across the top and that is all? I think you are not understanding what is going on. The gyre, by design, gets the whole water column rotating. Hence the "gyre" name. The goal being flow across the tank with no dead spots. Just take a look at the bottom of the tank.

Yup. One Gyre 130 eliminated all the dead spots at the bottom of my tank as well as getting me great surface agitation.

Yeah something important I think people don't realize is that the gyre works best when run at a continuos speed for an extended period (hours). This continuous flow gets the whole tank water column moving. Not just flow directly from the pump. I see people running them in pulse mode and I don't get it. For me constant speed alternating between two gyres creates great flow across the entire tank that prevents detritus from building up and results in even coral growth.

Quick video showing the flow in the opposite direction along the bottom.
XF150 at 50% with rugged impellers on 4' tank.

Yea because if someone owned one and it was in fact garbage in every aspect you should just ignore the Facts.

The above facts that people have mentioned as to why they are junk. Why in the world would someone take that with a grain of salt.

You are the only one who said they are junk. That's the only fact I see. I have 3 and I think they are awesome. More people on this thread like them than do not.

I could find hundreds more in other threads but take that with a grain of salt

Most of those are opinions not facts.
I have dealt with both and found the customer service to be the same. I have mp40s and radions in addition to the gyres.
I'm not saying that mp40s aren't great products. Just that I have both and prefer the flow pattern provided by the gyres.
Things become tried and true by running for long periods. They need time to do that. The gyre is a new product. That doesn't make them junk.

Listen I'm just saying you shouldn't tell someone to basically ignore common issues with a product. Because they absolutely shouldn't. I have not had a good experience with gyres, which doesn't make them Terrible however just because you have had good experiences doesn't mean he should go buy one either and should ignore all the bad reviews. These pumps are not failing due to user error, and there are obvious flaws with them just look at the reviews it's not a secret.

But you do state that they are junk.
I didn't tell anyone to ignore anything. The issues you are referring to have been resolved. I provided useful information about them. I didn't say they are the best you must buy them. Just that I prefer them over my mp40s. They are IMO far superior in terms of the flow they provide. This is the most important factor to me.
I'm not going to count the number of good vs bad reviews on this or any other forum but I would say most people do not agree with you that they are junk.

And I should add I've had mine running since NOV 2014 with no failures. Didn't realize it had been that long. One motor block was replaced due to the cable issue they had. It continued to work fine so I'm saving it as a spare. I did break a few props (just small breaks in individual blades after which the pump continued to run) due to snails crawling in but this was resolved with new props.

I had the exact same results. I definitely was not a fan of exposed wires in the aquarium, the jacket that covers the wires is complete garbage. Mine wore out before the one year warranty was expired so I could've got A new one at no charge but didn't want to take the chance of getting electrocuted so I just pitched it the garbage and went back to my MPs.

I don't understand this? The cable is an acknowledged flaw in manufacturing the early gyres. It has since been fixed. And while in theory 36v could electrocute you . . . No. It isn't an AC pump.
