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.

 
We use almost all Rigols at work. My slow bench scope is a 500 MHz
DS4034 (upgraded from 350 MHz)

and my fast scope is a Tek 11802 sampler.

I also have one, 11801C. Couple of SD-24s, SD-20, and SD-22 heads :)

At the original purchase price, adjusted for inflation, I must have
half a million dollars worth of sampling heads.

The color grading and jitter measurement is great on the 11801C, but
the old B+W screens photograph better.

I'll miss my 11802 when it eventually dies.

The TDR is great. I'm going to give my new kids a lecture on
transmission lines, and I'll show them some TDR.

It is apparently possible these days to get an EE degree and be
completely ignorant of transmission lines. Or even electricity.
