I have a 3000T series and its bigger cousin 4000A. A few years back I had Yokogawa, RS in the lab for evaluation. Tek fan for about 25 years then ditched them for Agilent / Keysight. Wasn't a fan of any of the UIs. You were always taking more steps than you would on an Agilent to get the job done.
While the noise floor on the Keysight scopes is not that great, as mentioned, no one compares in the area of responsivity of the UI. On the 3000T, I think they really got it right in terms of touch sensitivity, key sizes, etc. The zone trigger, when you need it, is a thing of beauty (frequently, not always).
Forgot the LeCroy I was stuck with for a year in a recent position. It was in the WaveSurfer 3000z family and a POS. Somewhat crippled in the function department. When I contacted LeCroy support, thinking I was missing (in my mind) how to access that function or measurement, LeCroy's answer was that it's a cheaper scope and doesn't have features of more expensive units.
Hello
We also has $495 Rigols which would run rings around the LeCroy (in many areas). The missing function has been pretty basic fare for 10 years or more.
As mentioned, the Keysight Megazoom, to the best of my knowledge, is still unmatched. This, along with the overall UI response mentioned, never makes you feel like you're waiting for a slow computer.
Almost forgot ... being old school, I worship independent vertical channel controls. While the 3000T and other touch capable scopes let you move the traces at will, those with one knob thats shared kinda s-ck.
