It is not easy to compare CRT's about sharpness and brightness because you are limited by the risk of burning the phosphor and there is no way to measure it.
Then, it is a bit subjective.
But I think the best CRT I know is the one of my Hameg HM 1505 (150Mhz)
The CRT of HP1740A is also very good.
A great feature of the HM 605 and other HAMEG analog oscilloscopes is the component tester.
It works like the HUNTRON tracker and is very useful for repair.
The 465 / 465B are very reliable, far more reliable than the 2235.
I recomend to install a fan in your 2235, like the 2236, because SMPS works very hot.
475 has 3 time bases, 2 mains (slow and fast) and 1 delay and is more complicated than 465 for this reason.
Probes of higher bandwith than 100 Mhz are expensive ...It is a nonsense to buy an high bandwith oscilloscope (200 or more Mhz) and use it with 100Mhz probes.
The 465/475 was designed to fit under aircraft seats.
So far I know, it was the 2335/2336/2337 not the 465/475.
HP\Agilent 546xxx are digital and not analog oscilloscopes...Not as simple as an analog one....their weaker point is the display : it is a little monochrome TV crt that has not a very long lifetime and hard to find.
