Mine is a 2 in 1 and I love it. Julia loved the swing, hated the bouncer, Emma loved the bouncer hated the swing, so it has gotten great use. And I loved not having to store multiple items (we were in tiny apartments until we left NYC this summer, so storage was a huge issue).
DS loves his swing and to be honest we never used it as a bouncer. It does detach easy though if we wanted to. He just isn't the type of baby that likes sitting still so we always kept it as a swing.
