The verdict
One removes scratches. The other removes the marks the first one left.
Ultimate Compound is a one-step cut-and-finish for daily-driver paint where you want haze and light scratches gone in a single pass. M205 is a true finishing polish — it removes the haze a compound leaves and brings the gloss the rest of the way up on show-grade paint. On most cars, the compound is enough. On the cars people walk around twice, M205 is what gets them to do it.
