Is Mercury trine Saturn a good or bad aspect?

Aspects aren't moral. Mercury trine Saturn flows — which is comfortable, and sometimes too comfortable to push you anywhere new. Read it as a description of what's actually happening, not a verdict.

What's the difference between a natal aspect and a transit trine?

A natal Mercury trine Saturn is wired into the chart for life — it describes a persistent pattern. A transit trine is temporary: the sky's Mercury forming the same angle to your natal Saturn (or vice versa) for a window of days or weeks. The mechanics are the same; the duration and intensity are not.

How tight does Mercury trine Saturn have to be to count?

Standard orbs in modern Western practice run roughly 8° for Mercury trine Saturn when the Sun or Moon is involved, 6° otherwise. Tighter aspects (within 2°) read louder; aspects outside 8° tend to fade into the noise of the rest of the chart.
