Everybody's needs / experiences with cases and gig bags has the potential to be unique. Those of you who exclusively use cases, that's great, because that's what works for you. For me, gig bags work best. I haven't used a hard case at a gig in at least 15 years. And that last time was because I needed to fly to Florida and so I needed to check my Alembic 5 string.
I prefer gig bags for transporting all of my basses to gigs. That includes a 5-string Point Alembic and a 4-string Omega. The bag that they live in is a leather bag that was the prototype for the leather bags that Alembic used to sell at the Alembic Store. It is very well padded. I did add a little more padding to the bottom of mine, though because the point tends to focus the weight stress onto a very small area. This was more of a preemptive move on my part to head of long term wear.
The reason I like gig bags over hard cases is that they provide me an extra dimension of control of my instrument. When we are loading or unloading equipment, I know EXACTLY where my bass is. It's on my back. It also frees up my hands for dealing with other equipment, the occasional beer, signing autographs (j/k). Sure, hard cases provide more physical protection, but ime, a sufficiently padded gig bag provides the best balance of physical and possession protection.
