CNCTech,
While I'm a 400 bigot (unashamed), when talking about Pro's and Con's from a OW standpoint, I believe its a bogus question.
OW does not really exercise the frontiers of SQL or databases, with the exception of when you have terabyte databases.
I believe the decision on which DB is more appropriately approached by where your skill set is. My anology is normally a British car vrs an American car. Both will get me from point A to point B. However, it is much easier for me to drive an American car as everything is on the 'correct' side of the car, from my standpoint. If I was British, the American car would not be as good a choice.
Can I learn to drive the other type, of course. Is it cost effective, maybe. Do I have other constraints, ie time, money. Probably.
This is why I try to recommend that people follow their skill sets.
Now if you have no skill set to start with....Go AS/400 (whoops, another flame war) <VBG>
JMHO
