Just the fact that we can even mention MXO4 when comparing function parity is telltale sign how good little Siglent is. MXO4 costs 5-10X more..
But even on base specs they are quite different oscilloscopes. For example
- the SDS2000X HD has bandwidth of 100 - 350 MHz, MXO4 has bandwidth of 200 MHz to 1.5 GHz
- the SDS2000X HD has max update rate of 100,000 wfms/sec, MXO4 has max update rate of 4,500,000 wfms/sec
- the SDS2000X HD has max memory depth of 200 Mpts/channel, MXO4 has max update rate of 400 Mpts/channel
- the SDS2000X HD has max sample rate of 2 GSa/sec, MXO4 has max sample rate of 5 Ga/sec
As per Siglent, the highest end model (SDS2354X HD / 350 MHz) is 4,145 USD. A 350 MHz MXO4 (whose base specs are over twice that of the Siglent), lists for USD 13,400. So not exactly "5-10X more"

And there is a LOT more to a scope than even these base specs. I would invite you to do a side-by-side compare of FFT functionality, for example.
Not casting shade on Siglent - they have come a long way - but the model that you mention isn't anywhere close to being a competitor to the MXO4.
R&S is legendary company, and I have great respect for it..
Hence the statement:
Just the fact that we can even mention MXO4 when comparing function parity is telltale sign how good little Siglent is. MXO4 costs 5-10X more..
I wasn't saying it was competitor. That is obviously not the case.
But this is something that A brands seems to not understand well..
Form a marketing perspective A brands make these (frankly arbitrary) categories.
So Keysight makes MSOX 4000 that is pretty much identical to MSOX3000T (4000 has one more AWG CH, bigger screen, slightly more BW on one model but with same sample rate so you can use it only with2 ch enabled,and some more little things of difference) and then the call 3000T upper low end class and 4000 a midrange scope.
To me, as user all I see is bigger screen. You cannot measure anything more with it. It has no benefits (apart from screen).
To user, if 4000 is mid range so is 3000T/G, albeit slightly inferior. But there is pretty much no work you cannot do with 3000T that 4000 would.
To user they are same class of instrument capability.
We (customers) really don't care what manufacturers would like to classify them to be.
So if I'm happy enough with a 10" screen, I don't need FFT or triggers to be that fast and I'm happy with 500 MHz BW, SDS2000X HD can do MORE types of different work for me than MXO4 right now. In that case they are the same class of usefulness.
I know, and I stated that, that I'm fully aware R&S will develop the MXO4 to a proper beast, given time. I expect no less from them.
But you are correct, that partial and "pick and choose" "comparison" is not right. It just out of place. You are right. And it muddied the point.
I should have compared SDS2000X HD to RTB2000 or RTM3000 (500MHz version) and 2000X HD would still have many advantages and generally compare favorably to those two. They are much more expensive still. Good scopes though.
And that is, like you said, a statement how far has Siglent developed and has bridged the gap that was once quite substantial, in all segments.
Where R&S really shines is in the high end, where in many areas, not even the really big names can contest them...
Our eastern friends still have a way to go there....
But in lower and mid segments they caught up and even lead sometimes in some details.
