How to read this

Three tiers: flagship for quality-critical work, balanced for daily production, budget for bulk and experiments. Names track the current mainstream options — the landscape moves fast, so treat the tier logic (not the exact model list) as the durable part.

Rankings and prices checked — leaderboards move weekly; always confirm pricing on the official site before committing.
