A cabin case covers weekend and short business trips, a medium checked case covers a week to ten days, and a travel backpack covers hand-luggage-only trips or destinations with less predictable terrain. That three-bag set handles the large majority of real travel patterns without needing a case for every specific trip length.
Buying beyond that set — a large case for extended trips, specialized bags for sport or work equipment — is worth doing only once an actual, recurring need shows up, rather than in anticipation of a trip that may not happen.
