The Rigol's grid uses a cinematic 16:9 aspect ratio while the others are still using a "last-century" 4:3 aspect ratio.
Give me 4:3 any day of the week on a scope (if everything else is equal) or a minimum of 16:10 as the Cinematic TV aspect of 16:9 makes very little sense on a scope.
You can counter it by making the 16:9 screen extra big, but the differences are significant when I compare the screen on these latest 7" 16:9 Rigol products to an 8" screen in 4:3
It's a tad over 8cm vertical on these 7" 16:9 (83mm) and around 12cm on 8" 4:3. The horizontal gain is obviously less, and around 1 to ½ cm in the 8" 4:3 favor.
Even though it's just a 1" inch difference, the vertical gain is almost +50% bigger on the 8" in 4:3 vs 7" in 16:9.. That's quite a bit on that precious vertical axis, not least with Rigol's scope UI that seems to be eating more than 33% of the vertical ratio in UI secondaries, and not valid for waveform display - most other scopes seem to be between 15 to 20%.
