It's hard to critique anybody's gear selection, but there are three things to consider.

1 ride the gear that's comfortable n\for you in any situation. This is the main objective, but if when you have choices between two comparable combinations the following may help decide.

2- larger sprockets are more efficient, and produce less wear. So if you can choose between the outer and a larger rear instead of the middle and a smaller on, larger is usually better.

3- sprockets that are better aligned are more efficient, so outer with outer half of the cassette, middle with middle, etc. This isn't digital as in good and bad, just a matter of degrees.

Rules 2 and 3 are often in conflict since using the larger chainring may force you inboard on the cassette, and the middle with a smaller sprocket may be better. So throw it all into the hat and remember that rule 1 is what drives the process.
