Keysight offers 70, 100 and 200MHz models, R&S has 70, 100, 200 and 300MHz models. There are quite some below 200MHz, right?
I didn't mean Siglent only for this kind of low bandwidth models but it's an ancient old marketing trick that no vendor can resist: Look we have this sky high feature and the prices of some of our models start only this low and then they expect people to connect these 2 things. Surely it works for many people but does it work for people who do engineering stuff (where logical thinking and good memory is basic pre-requisite)? Anyhow, unless these models can be hacked (mainly an option for hobbyist only) they probably sell quite badly.

Enterprises can negotiate some (artificially) expensive options for free and feel like a winner.
Siglent of all brands, appears to have a mostly reasonable marketing strategy. Price premium for higher bandwidth is bearable except for the SDS5000X, where the higher bandwidth models actually have a more costly frontend compared to the 350MHz model.
With regard to options, the Siglent scopes are fairly complete from the outset. There are no memory options and almost all software features are standard, only exception would be some exotic packages like Power Analysis. All the popular serial triggers and decoders are included for free and the rest is reasonably priced, even on the SDS5000X. This is also true for the MSO option.
Even enterprises don’t have unlimited budgets for their T&M requirements anymore (some never had) and this is even true for the aerospace industry. Even big companies do not need high end scopes for all their departments, all the more so as today even entry level instruments offer performance and features only found in top end devices not too long ago. Given your statements, I guess you would be flabbergasted if I you knew the percentage in the Siglent sales statistics which are enterprise purchases these days…
I'm sure there will be plenty of great features but the shared control

I have no problem recommending the simpler Siglent gear (if it has mature firmware) to customers but oscilloscopes... no. There is just no way to smooth over / explain the limitations on the oscilloscopes I outlined earlier. The people I deal with have used other equipment so they know how an oscilloscope is supposed to work.
The memory selection on the Siglent DSOs allows to intentionally lower the sample rate – only at slower timebase settings of course, because the minimum is 20kpts in interleaved mode on the SDS2000X+. The main purpose of this is to control the maximum number of segments for history and sequence recording (FFT has its own length selection by now).
Of course, offering everything at once and having it all configurable to meet everyone’s taste and habits would be the ultimate solution
But what is the purpose of history mode? I've seen this on a Yokogawa oscilloscope and R&S has it as well but I don't really see a particular use for having a history. If you want to acquire segments then you might as well turn on segmented recording.
how many bits is a point in SDS2000X Plus and SDS5000X if you save to a file?
And if you use 10 bit on SDS2000X Plus does it change the memory size in points?
If you use hi res mod (Eres) is than a point more than 8 bits?
And if yes, is max memory than smaller?
And if you use the Digital Channels affected this the memory size of the analog channels?

Segmented recording is a special mode for optimizing memory usage and minimizing blind time for events with irregular occurrence. It is set up on purpose and has no real time screen update.
History can replace sequence recording for regular events or in general, whenever minimum blind time is not paramount. Infrequent serial messages would be an example for this. We choose the record length so that we always catch a command/response pair (assuming that they are closely spaced) and can use zoom if we really want to look at some details, in short: just work as usual. But we can also stop the acquisition anytime by entering the history, where we can closely inspect not only the current record, but also all the command/response pairs from the past.
