I just used a fully digital oscilloscope for the first time

The TBS2000 is way nicer.  I looked at the manual for the TBS1000B and it appears to be very similar to my TPS2000 except for the isolation feature.  There are currently 3 scopes living on my bench--a Tek 2221A (w/ A6909 isolator), a Sigent SDS2354X+ and the TPS2024.  I'd say for most simple tasks, the TPS2024 and the 2221A are roughly equivalent in many ways.  The persistence/DPO feature on the TPS is weak whereas the 2221A obviously has an analog mode.  The TPS does have a basic but functional FFT and autoset/autorange (like the TBS1000B) as well as basic digital features and automatic measurements.

I couldn't figure out the point of this post.
Considering the price of the Tektronix 1072b, I don't think it's reasonable.
Was it released in 2015?!
Based on its specifications, you can get much better for less.
Almost any Siglent or maybe a Rigol or two seems like a better choice.
Maybe even an Owon is better than this Tektronix..

"There's no obvious indicator that the trigger is set to channel 2. Trying to decipher that takes forever"
From the few videos I found about it, its use seems clear to me, I don't understand what your problem is with the trigger. In the lower right part of the display, when you switch the trigger to CH2, does the color of the text not change, or does "CH1 / 0.00V" not change to "CH2 / 0.00V"?

"Getting the beam centered around zero, I couldn't find a quick way to do it,"
Can you press the vertical positioning button? On my Micsig and Rigol, I can use them to center the zero point of the channel in the middle of the screen.

I would like to look at a digital scope where all the functions have their own buttons and knobs, would a surface of half a square meter be enough for a modern scope?

No.

The Analog scope is orders of magnitude faster.  I knew the digital scope might be a bit slower, but not to that ridiculous extent.  Even the autoset ranging was slower than simply dicking with the buttons.  The digital scope was so slow I'm genuinely surprised analog scopes were discontinued in the mid 90s and didn't continue production/development/refinement to this day!

If I were working in an environment and someone took my 2230 away and gave me something as slow and clunky as that digital scope, I would have revolted.

I'm agnostic on the interfaces, and I understand different paradigms fundamentally work differently, but holy hell sometimes you shouldn't throw the baby out with the bathwater when embracing new technologies.

Of course the example I used might have been especially slow, meant for the education market. I looked at a review of a newer keysight scope, and it looks way way better, but it's also three decades newer.

Much of the speed will depend on whether they have competent programmers who use C, or whether they use fairytale programming languages.  Unfortunately, that that doesn't seem to be the case!.

Having used a DS1054z I wouldn't use my analog scopes anymore unless I am feeling nostalgic.  I wish I could afford the modern high bandwidth oscilloscope so I wouldn't use my TDS744.
