At the same price? Not a chance.

You'll have to go up quite a lot in price to get something better. Think: The difference would buy a good multimeter, a soldering iron and a bench power supply.

(And the oscilloscope still wouldn't be perfect, you'd just have other things to worry about)

OTOH you could even go down to a 500 Euro oscilloscope like the Siglent SDS1204X-E. It's probably all you need and you'd have enough money left over to create an awesome lab.

(Ever wonder how "ringing" can occur before a signal starts to rise? Undersampling combined with sin(x)/x reconstruction...)

Meh, ringing on step responses isn't usually Gibbs unless something has been designed or set wrong.  You can have ringing (and even pre-ringing) on an analog scope.

It can be a mixture of both.

But you can't have Gibbs.   ::)

Yes I know, this is one of my doubts. I will check some review of that scope but in the mean time what do you think about its bigger brother sds2000x-plus?

Here I am, I did the test you asked for, please let me know whath do you think about It.
Thank you very kind!

Photos:
1) 1mv/div, no probe, 20Mhz BW limit, 1x
2) 1mv/div, probe, 20 MHz BW limit, 1x
3) 100mv/div, no probe, all the same
4) 100mv/div, probe, all the same
