I'm still mainly interested in the Rigol vs Siglent 2-channel scopes, but you have to keep an open mind too. at the moment it's not clear which way to go. Finding informative opinions must be the way to resolve this dilemma...
A friend recently bought the DS1202Z-E and it's very impressive for it's cost, though the price difference between the SDS1202X-E and the DS1202Z-E is pocket money, so the obvious choice is the SDS1202X-E imho if you only want 2 channels.
However I'm going for the SDS1104X-E, as it has 4 channels and dual ADC's (And has the option of adding a AWG and MSO later on)

Those without a need for raw BW are quite well served by the good bit cheaper SDS1104X-U.
I am genuinely interested in the AWG option, especially as it is isolated. But I cannot find much information about it and real world use.

Dream up some challenges.

Maybe you should start a SAG1021I thread to keep it altogether should others like to contribute.

I was looking at the MSO option but I have also come to the conclusion that a 4ch DSO has some advantages over the MSO:
1. Checking signals on an i2c or spi bus "looks about right", then analog scope can confirm levels are OK;
2. Extra channels from the MSO make the display more than a bit crowded;
3. Looking at a serial bus vs a 16-bit bus is as well served by 4 channel as 16;
4. Highly integrated chips don't generally hook up with a parallel bus - 4 channel is more than adequate.
Rigol 4 channel 100MHz scope is slightly more expensive (£25) than the Siglent but the cost of adding the MSO is much cheaper (£180) and as well as the H/W there is no license required. The Rigol has 1 gs/s, 500 M/s and 250 M/s for 1, 2 or 4 channel so is closer to the -U version of Siglent. I'm not sure how they get to over 100Mhz with 4 channels running with only 2.5 or fewer samples - seems like guesswork. It has been commented before that sometimes paying a small premium for Siglent is justified.
Rigol vs Siglent also comes down to preference of the user interface. I do like the side buttons on the Rigol and the selection of measurements, but also the soft buttons underneath on the Siglent. Both scopes seem to have crowded the screen on the LHS and RHS so that the waveforms are smaller than they need to be and (as I read it) no option to hide the soft menus? The two-channel Rigol has combined the vertical V/div control with a 2 button selection whereas the Siglent stays with two separate controls. When you see the Rigol power-up, you immediately see green lights under the blanked-off areas suggesting it takes advantage of a common circuit board and an overlay that restricts the design.
There is a real danger that I may overthink the purchase and get more than what I need. That said I feel more comfortable with the Siglent 4 channel SDS1104X-E over the SDS1104X-U. In the US they aim for a $100 reduction but in the UK there is only a £50 premium. A scope is one of those things, where trying to economize now, can easily backfire later. When considering the price, where you buy it in the UK affects the total price (discount and delivery) so that has to be factored in too.

The price of the SAG1021I is high enough that it's just not worth it.

It clearly isn't controllable directly. That thread with using FY6900 with Siglent scope uses PC in a loop, and a piece of software.
Which is great if you happen to already have them both, and you just want the functionality and you don't mind additional effort and equipment being used.
Beauty of the Siglent scope + Siglent AWG (not only SAG, but also SDG1000X, 2000X, 6000X) is transparent work in FRA.
It simply works. Just connect network or USB.
How important is that to anybody, it's their choice.
Some people might decide they don't need the FRA at all and that even a simple analog function generator is enough for them...
On both models bottom left of the display is a small round white button that toggles the menus ON and OFF.

So far as I can see, Rigol has soft menus on both LH and RH side without the option to hide them. Menu on/off on Siglent removes menus on the bottom or also on the RHS?

regarding handling of the scopes .... only the 4-channel X-E types feature the integrated webserver.
I returned a 1202x-E and got a 1104X-E instead due to missing this feature.
A feature I haven't seen any talk about is the preset key which allows to put the scope into a user-configured preset condition or a factory default. Quite useful in education or certain production processes.

This has been suggested to me https://www.sjelectronics.co.uk/brands/gw-instek/gw-instek-gds-1054b-digital-storage-oscilloscope.html
I can't honestly say I like how it looks, but the spec is OK for the price.
Only the bottom menus can be hidden as they don't show the more important RHS operational settings while the bottom settings show far less important info unless you're documenting screenshots or coming here seeking help where the more settings you can show is more helpful for us to give guidance.
I get that there is a hack for setting it at 200MHz BW, perhaps there are downsides to doing that? I read that the supplied probes rated at 100MHz are actually quite good ones, so no need to rush to replace them even with the hack
