I totally agree. I've always maintained that hard cases are useless unless they have good padding inside them. If you have any kind of hard shell, and you hit it hard with something, the shock is just going to translate directly to whatever's inside. Plus, the cargo's going to bang against a hard surface if it's not secured well inside.
For this reason, I think that a well-padded gig bag actually provides better protection than a flimsy hard case with minimal padding. Granted, the gig bag can't have anything heavy stacked on top of it, but this isn't a problem for short-distance travel where you can monitor the cargo yourself. The gig bag will probably also be a bit lighter, which will lessen the impact if it's dropped (and also make people less likely to drop it).
On the other hand, flight cases are the best of both worlds - lots of padding, and a hard shell. The only issue is weight, but this is a reasonable compromise when flying, sailing, or travelling by bus/truck.
If you're just travelling locally (rehearsals, recordings, etc), you shouldn't need anything more than a solid gig bag, and flight cases provide ideal protection for situations where baggage handlers and port workers will be throwing your equipment around (or stacking crates on top of it). This is why I currently only own a Mono M80 Double big bag, and am planning to buy a Rockcase Multi-Bass flight case - I'm covering both ends of the spectrum. The conventional hard case fits somewhere in the middle of this spectrum, but it's ultimately pointless because you can just start with a really good gig bag and get a flight case later (as you're not likely to be touring within the first few years of learning to play).
Another reason I like gig bags and flight cases is that they let you carry multiple basses in one case. I've been carrying 2 basses for years, as I don't always have time to change strings and I've had electronics die on me at rehearsals. You just never know what's going to happen, so it pays to have spares of EVERYTHING. It's great that more companies are making double gig bags these days (Mono and Gator in particular), and there are a few that make flight cases for 3+ basses. It seems like musicians are getting more savvy about operating efficiently, and it is A LOT cheaper to carry a single 3-guitar flight case than 3 individual flight cases (both in terms of weight and space). I've seen a few bands using Scott Dixon flight cases, which seem to be the industry standard for those who can afford them as they're top quality.

Dual Electric Bass
The hard case which came with my G&L is very nice. It's stiffer than the average cheapo hard case, with lots of padding, and a thick and soft furry liner. If the bass is not being played, it resides in the case.
