We start with oscilloscope DC vertical gain accuracy and the lack of an AC accuracy specification. Combining that with the scope's frequency response you can get a good picture of overall accuracy.

Oscilloscope channel-to-channel isolation - when you provide a stimulus on one channel, what happens on the other channels?
Offset range - how far up and down can you move signals?

Mixed signal oscilloscope's digital channel specifications
Bandwidth isn't specified for digital channels. Instead, the toggle rate is specified in seconds.

Horizontal specs
Timebase accuracy - is a warranted spec in ppm. As electronics age they start to become less accurate.
timebase delay range - how far can you horizontally offset a signal? If you're trying to collect more than 500s of data, you'll need to go with an external trigger in to trigger your oscilloscope.
delta time accuracy using cursors - a combination of lots of different accuracy factor.
Oscilloscope acquisition modes - Normal, High Res, Averaging, XY mode.
People don't use XY mode very often, but people who do are very passionate about it.
