The Antec is pretty good. If you want to step up to a higher tier model, this one is available for a bit more cash-
That PSU is a rebadged Seasonic Focus Gold. The Focus Gold is under the Tier A under "( low priority units - minor issues or lack of info ) " so it doesn't make sense that the Antec EarthWatts Gold Pro would be a Tier B. Overall the Antec EarthWatts Gold Pro is a good PSU that will a long time.
Another choice would be the Fractal Design ION+ https://www.newegg.com/fractal-design-ion-fd-psu-ionp-660p-bk-660w/p/N82E16817580022 which is cheaper than the Super Flower.
It has a plain sleeve bearing fan, that's why it's tier lower than regular Focus based units which mostly use rifle bearing fans.
The Antec uses a Fluid Dynamic Bearing not a sleeve bearing fan.

It's technically rifle but yeah, i thought it's a sleeve on EA Gold Pro ... It will be moved to tier A in the next revision then.
When you get into specifics, rifle & fluid dynamic bearings are nearly identical. The rifle bearing is just a way to get around the patient of the fluid dynamic bearing. That said "It [fluid dynamic bearing] is a modification to the standard sleeve bearing to improve the lubrication of the bearing, and thus increase the life span of the fan while retaining one of the most positive aspects of sleeve bearing fans, which is the low noise level.

I'm aware, but most so called FDB bearings out there are actually rifle, i.e not patented type of FDB with grooves on the inside surface but on the outside (and I honestly have no idea how that's supposed to help anything). But eh, if its has a lifespan longer than your regular sleeve then something were made right obviously.
So you're saying that other Seasonic Focus / Prime SKU can have real FDB too ? Somebody needs to do a teardown ...
