Each is a different tool for different tasks and all three complement each other. IMO every bench should have at least one scope. In the past I have used a 2235 daily and found it to be a decent tool. I have also used some of the low end Tektronix digital scopes. From my experience the digital scopes are great for digital but I prefer analog scopes for looking at analog signals. The digital scopes I used tended to have a little bit of lag from the processing which annoyed me. Analog scopes are near instantaneous. I'm sure recent digital scopes are much faster, so YMMV as they say. I have a Tektronix 468 on my bench at the moment.

I'm just getting started in the hobby of experimenting with RF devices. I already have a NanoVNA and a TinySA Ultra (not out of the box yet though). In setting up my radio bench, what do you experts say about the need for an oscilloscope also? Will the devices I have cover most common needs or will I at some point wish for an oscilloscope also?
If you'all recommend the scope, I have a choice (in my price range) between a refurbished Tektronix 2235 AN (100Mhz, 2 channels) and a new import - the
Siglent Technologies SDS1202X-E 200 mhz Digital Oscilloscope.? Which of these two is preferable?
