A martini glass looks precise, but its wide V shape can feel fragile in a crowded room. A coupe is usually easier to live with: it is shallower, more stable, and works for sours, stirred drinks, sparkling cocktails, and small desserts. If you host often, buy coupes first and add martini glasses only if you truly love that silhouette. The best first stem is the one you will actually reach for.
