I was glad to find a neutral shoe that doesn't invade my low arches. The common assumption is that low-arched folks all over-pronate & need stability. I have flat feet, but I don't over-pronate so I need a neutral shoe. Because I have flat feet, I don't want a sole that's pushing up under my (small) arches when I run. I'm 200lbs, so I need some cushioning. I found the answer in Glycerin 8. Not to say they aren't great for high arches, too. I wouldn't know.

The shoe is snug, but expands easily enough to allow your toes to spread w/o causing too much friction or play. The back of the sole angles up a little so you're not doing the kuh-klunk heel-toe strike. The front of the sole is noticeable sloped upwards, which makes for a quick turn-over. Although the sole is thick & cushioned, the toe-to-heel rise is not as pronounced as on some Asics (like stilettos) which also cuts down on the kuh-klunk heel strike. Much appreciated for a former minimalist.

The Ghost 3 is another great option, if you are a lighter fella. I just find the Glycerin is better for a bigger guy/gal.

I didn't give the shoe a 5 because there's nothing special about the shoe to warrant the (formerly) high price. I definitely wouldn't part with $130 for the newer version. They are simply well-cushioned. Aside from that, the sole is beginning to show wear sooner than expected. The interior materials feel cheap on my toes. They don't seem like a flagship shoe. Although I quite like that they don't look at gaudy as Asics, they're so nondescript as to be mistaken for K-Mart specials.
