OK, perhaps things are different there. That doesn't help here--I don't know of any dealers that will provide demos for stuff like that and the only other alternative is to abuse seller return policies, such as Amazon's 30-day period for alleged defects. Otherwise the buyer is going to be paying for shipping, perhaps in both directions. And to add to that, it appears at first glance the the MSO/AWG promotion is only available directly from Siglent. Anyway, it wouldn't matter to me--I really prefer a 6-month or longer test period because I'm only an occasional user and it takes me that long to really get used to things and discover annoyances.

Ofcourse you need to come up with some kind of test plan you can execute in a small timespan. Just like you take a car for a test drive; take it onto the highway, take a few sharp turns, drive over bumps, see if it brakes properly, etc, etc. However that does not always rule out hidden problems which -unfortunately- Siglent and Rigol are prone to.

That clearly shows :) otherwise you wouldn't be so positive about it. Where it comes to the UI neither Keysight or Siglent are the best choices for non-touchscreen scopes. I used to own an Agilent MSO7104A but once I got the GW Instek GDS2204E the MSO7104A got abandoned quickly by me. The GW Instek is so much easier & efficient to work with. I sold the MSO7104A a long time ago; the GDS2204E is still used regulary.

Poor analogy.
What asset can you leave with an equipment dealer so to take home an instrument and put it through its paces ?
Best you bring a DUT and test the instrument at their premises to decide if it meets your needs.

What do you mean? Just get a demo unit and return it when done. Same with taking a car for a test drive.

A proper test of an oscilloscope takes over a day to work through. And there might also be some unforeseen outcomes that need further investigating whether it is user error or a limitation / bug in the instrument. It is not a matter of applying a few signals for 5 minutes and be done with it. Just look at the oscilloscope reviews I've done over the years. A lot of testing has gone into each of them.

What is, then, and why/how? Where the Keysight seems to do better than anything I've ever seen is with respect to UI responsiveness. Everything I've ever seen, including the limited amount of time I've played with a 2000 series scope (when I said I had no experience at all with "the Keysight", I was referring to the specific one here), is that the UI responsiveness is instantaneous, or so close to it that it doesn't matter. Maybe there are certain circumstances under which the UI on the Keysight will lag a bit but I've never seen or heard of it.

If my experience with the GDS-1054B is any indication, the GDS2204E is going to be very responsive as well. But I have been able to make the UI on mine pretty laggy with the appropriate acquisition settings, ones that I wouldn't regard as unusual, and wouldn't expect things to be different on the GDS2204E because such things tend to be architectural in nature more than anything else. Computers, and by extension these scopes, are many orders of magnitude faster than the demands of any UI, but arranging things so that the UI remains responsive under essentially all circumstances requires proper architecture from the beginning.
There's more to a UI than just responsiveness, of course, and the Instek appears to be more aligned with how you think about using the instrument than your Agilent was. But at least with respect to responsiveness, I know of nothing that beats the Keysight, based on plenty of videos of people operating them combined with my (admittedly very limited) experience.
There seem to be some that appear to come close, such as the Tek 5-series. Once the scope is able to respond within, say, 1/60 to 1/30 of a second, there will be hardly any more benefit to additional responsiveness.

Responsiveness doesn't do you any good if you need to press 5 buttons versus 3 buttons on a non-Keysight scope.
