Dojet driver - great post and you have some great points as well. It really does depend on a specific regional/major when comparing stuff.
That said - it's really very simple overall. If you are a regional "lifer", a regional will always be a better deal for you than a major due to your seniority and the ability to make quite a decent living staying there.
If you are not a lifer and looking to move on, I'll second what has already been said before: your worst day at a major is WAY better than your best day at a regional, hands down. It is really that different. You will figure it out when (if) you make the leap.
As far as comparing a DC-9 to an RJ - no comparison. Flying a DC-9, while technologically challenged (and flying similar routes to an RJ), is not about the size, or the old-school stuff. It is about the legacy of the aircraft itself, and it s history - chest-hair-growing material, if you will. Those that have flown it understand. Consider yourself VERY fortunate if you ever get a chance to fly it.
