FYI
All the Siglent scopes listed offer Bode plot capability as std.
Can confirm SDS1000X HD options can be unofficially enabled and for this model series just protocols I2C, SPI, UART, CAN, LIN decodes will be available.

Where do you get that number from?
My Siglent SDS1104X-E has 56 µVrms noise for full bandwidth and 27.3 µVrms when 20 MHz bandwidth limiter is active (measured at 500 µV/div). Regarding noise, it is in a similar ballpark as the SDS2000X Plus, yet suffers more and stronger spurious signals.

To the best of my knowledge, the basic serial triggers and protocols (UART, I2C, SPI, CAN LIN) are free on all Siglent models. Only the more specialized protocols are paid options.
Bode Plotter is a free option as well - you don't even need the AWG license to use the internal AWG for that.
In general, it's questionable what value such a table is. You look for a tool for a certain tasks - and the only thing that really counts is getting one that helps you accomplishing that task best and most effectively.
For example, you dont need a super high waveform update rate at all, but a powerful FFT can help a lot. You didn't even include the FFT in your table. Max. length? Speed? Tools? Yeah, most datasheets won't tell you that in detail anyway.
So if it just were to decide between the two Siglents, you can always look up the numerous demonstrations for both scopes in this forum to get an idea how powerful they are - also with their class-leading 2 Mpts FFT.
You can also listen to the ones who have evaluated the top HR model from Rigol (DHO4000) and tell you that its FFT is very basic and not impressive. And nobody has ever checked the accuracy of the measurements.
Or you listen to those who have never touched anything above a DS1054Z but still tell you how good the DHO800/900/1000 are. Maybe that's even true. But since you get only claims instead of hard facts and demonstrations, it remains a gamble.

I have put the FFT in the table, look well, I have been researching on the internet to obtain the background noise of the SDS1104X-E and the only thing I have found is that it is:
Table 8 Noise Floor Limited Range for 2-Channel
Volt/Div Stdev Limited Range
500 uv ≤ 250 uv
link:https://int.siglent.com/upload_file/user/SDS1000X-E/SDS1000X-E_ServiceManual_SM0101E-E01A.pdf
and where do you get that it has 56uVrms ( better even than the $4,600 12-bit 350Mhz SDS2354X HD which has 70uVrms)
It is clear that my oscilloscope and yours, even though they are the same model, have different characteristics.

65µVrms, look at the datasheet.
And: Noise rises more or less with the bandwith.
Plus: The difference between 56µVrms and 65µVrms is....nothing.
Plus, the second: You already have a SDS1104X-E, so you can measure it in real and now. ;)
At the moment I let the SDS1104X-E warm up for it...
