We like the Rigols.I recently acquired a Siglenthttps://www.amazon.com/gp/product/B06XZML6RD/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1and gave it to one of my engineers. I'll ask him how he likes it.It has an up-front DEFAULT button, which a digital scope needs to getyou out of nightmare states.

It sounds pretty good to me.

What's missing?
 
I like the 500 uV/div.

If you want to save the last penny, maybe. But you can get way better scope
for slightly more -- Rigol DHO800/DHO900. It is 12-bit, same 550uV/div, has
all standard serial protocols decoding, very light and compact, can work
from a battery with USB-C power connector, way better than that Siglent that
feels like relic next to those DHOs.

I don't have any relation to Rigol, just have DHO924S as a go-to scope on my
bench and DHO814 for use as an advanced multimeter wherever I need a
portable one. I like them and I can run them in a web browser if needed.

I do have an advanced LeCroy WR640Zi with all options for serious jobs -- it
is 40GS/s 4GHz bandwidth instrument with all features imaginable -- but I
rarely power it up. It makes a noise like a jet at takeoff (Rigol DHO is
very quite) and it is 8-bit so what you get on the screen looks ugly
comparing with 12-bit DHO. DHO924 covers 99% of real world debugging so
LeCroy is mostly gathering dust...

BTW, DHO924S has built-in Arbitrary Function Generator with 25MHz max and it
can make Bode plots using that AFG which is quite useful for SMPS debugging
and loop response tuning. Sure, it is not the best AFG but totally adequate
for most practical purposes.
