There is a debate as old as LCDs as to whether CRT or LCD is better for oscilloscopes.
The problem is complicated, but people argue that CRT is better because of the higher refresh rate, persistence effects of the phosphor holding charge, and no ADC quantization errors.
Most of those problems are more or less solved these days, though.
But you have to admit, there's a certain kind of elegance to old CRT oscilloscopes. You're effectively taking the signal you want to measure, and connecting it to an electron beam. Your signal directly alters the path of the electrons, which you see as a wiggle on the screen.
