The Super Flower made EVGA unit SR-71 Blackbird linked above is a better unit than the FSP made NXZT Hale 90 v2.
The NXZT gets a Pass from HardOCP. No awards, no recommended buy.

" Things then go a bit askew in the performance metrics as the unit had good but not great voltage regulation, good but not great DC output quality, very good Transient Load Test results, and was a bit louder than we would hope. All is not "just good" with this unit as one area that it did do well relative to it’s marketed position, and in general, was the unit’s efficiency. During our testing today the HALE90 v2 1000W easily made the 80 Plus Gold numbers it was advertised as having both in our testing and using 80 Plus' testing which is excellent. Now, where all these results that say good and very good next to these hurt this unit is when we look at the competition. Today, the HALE90 v2 1000W ranks below most comparable we have seen in the voltage regulation and then it is in the middle of the pack on just about everything else. This, by definition, kind of puts you in the middle to below middle of the pack overall. On top of that, those units it is trailing are all significantly older than this unit and this new NZXT HALE90 v2 1000W unit is priced right about the same as those units today at $229.99 compared to the Revolution87+ 1000W at $220.54 and the XFX ProSeries 1000W at $229.99. Certainly some users will find value here today, but overall without this units looks it is currently just another face in the crowd."
So it's decent but nothing special.
The EVGA however is a standout in testing from jonnyguru scoring a 9.4/10 and a recommended buy award.

" EVGA's second ever submission to this site just happens to be absolutely fantastic. The Supernova G2 1000 watt unit is stable, it's low on ripple, and it's plenty efficient. Just like the box said it was. And it's affordable, too. Folks, don't worry about the bragging rights the NEX1500 would give you... this right here is the EVGA unit to own, and I am really looking forward to taking a look at big brother 1300W before too long. If that unit is as good as this one is... look out, competition.
The Good:
•excellent ripple control
•excellent voltage stability
•affordable
•fully modular
•nice looking
•10 year warranty
The Bad:
•nothing, really "
If I'm building a system that needs 1000 watts I know which one of those I am going with.
