I would test it like nctnico did with his Korad.

Judging from a teardown of the Siglent load, it looks like the mains transformer is also relatively close to the analog control circuitry. But in the Siglent load the transformer is rotated by 90 degrees compared to the Korad load which could be better or worse. All in all it would be very interesting to see whether Siglent has a better design to deal with the magnetic field coming from the transformer.
BTW: Tony Albus has created a video showing the Korad, Rigol and Siglent DC loads:

I was taken aback by how deceptively hard it is to pick a good DC load.
I once thought that KS EL34243A fits my requirement to a tee. Half rack, dual channel, fast digitization, fast arb waveform, LXI, institutional purchase so no problem with their BS cust support... Yet the only "review" here is basically a trainwreck (for $5K instrument). I wonder if it is still that bad.

The Korad is "huge", so that could also be a criterion.
From what I can see, and also from your report, it seems to be amazingly well made for the money and the terminals are everything you could wish for.
Korad, you have to remember...
I have now ordered the Siglent load, should arrive later this week.
I'll report my impressions and tests here, I've also "heard" that you can "convert" the 1020X-E to a 1030X, which would be interesting in terms of resolution.
But that would only be an issue if I liked the load, otherwise it would go back.
At the same time, the self-build load will be pursued further.

Oh yes.
And "good" also means the ease of use, how easy it is to set the desired settings.
That's why the two new Rigol loads are in our cupboard gathering dust, while every colleague uses the ancient Zentro loads because they only have 3 switches and two pots... ;)

I doubt that is truly possible as the 1030X lists a better accuracy compared to the 1020X-E. Unless the accuracy is crippled on purpose, there must be better parts used in a real 1030X.

Skip the Rigols I'd say if that is the case. I have an older TDI DC load (1500W) which has a potmeter to adjust the current but the metering is not very accurate and you never really know where the pot is set to until you turn the load on. At some point I like to replace that one as well but I'm not sure I'd go for a Korad. But then again, it is hard to come up with an alternative that has good performance while being surprisingly cheap.

I expect you'll be reasonably happy with the Siglent. It's not perfect, but what is? And yes, it's trivially easy to convert to a 1030X with 3 SCPI commands.

Siglent makes good stuff for the money, that's why I have some of it.

To be clear, when I said "fan" I meant someone who used and seemed to like their products. I was not suggesting you were an irrational fanboy, LOL.
I myself am a Siglent fan in that I own several of their devices (scope, DMM, power supply, load), but I'm also a fan (so far) of my Rigol DHO1074 despite its rough edges -- at the price I paid, how could I not be? As long as it continues to serve my needs, I'll remain a fan. When it doesn't, I'll get something else. I'm certainly curious to see how the SDS1000HD plays out in the West.

Why would you think it not possible? It's been done to death for years now. Of course the accuracy resolution is crippled on purpose, same as with many of these instruments from Siglent, Rigol, and others. There is no hardware difference between them that I know of.
EDIT: You said accuracy, while I meant resolution. Still not aware of any difference between these.
