I am not sure “truth” or match to reality is a useful metric to apply to ideologies. Ideologies are mostly normative and prescriptive. Their two basic ways of failure are (1) produce a system which is unlike what the ideology wanted and/or expected; and (2) produce a system which you find unacceptable because of a major mismatch with your values.
Ideologies frequently make falsifiable statements. They tend to say X is true so one should do Y to produce good outcome Z. The statements “X is true”, and “doing Y produces outcome Z” are both falsifiable. Granted the statement “outcome Z is good” is harder to analyze given the current state of metaethics, but in practice one can get remarkably far just looking at the first two statements.

Ideologies rarely make easily falsifiable statements.
Karl Marx said that a proletarian revolution will lead to heaven on Earth. This is a falsifiable statement (and it was successfully falsified), but in order to falsify it you have to try it which is often all an ideology wants.
The difference is I believe that some ideologies are truer, i.e., better correspond to reality, than others.

Agreed, my point is that it is still meaningful to speak about ideologies being right or wrong.
That’s not a difference.
