If you are more adept at controlling the spinning tackle, then rig them up and use them...

Here are some potential combos, given what you have. There are a couple in here where the spinning tackle is preferred:

Spinning (Medium Rod) - Weightless fluke, donkey rig, or Topwater
Spinning (Medium Rod) - ShakeyHead or DropShot (or combination of the two)
Spinning (MH) - Wacky Jig or Weightless TxRig
Spinning (MH) - SpinnerBait or Smaller Cranks (heavier line)

BaitCast - TxRig
BaitCast - Moving Bait

I have taken several people out who used only their bait caster while I use my finessed rigged "fairy wand". I can't remember a time when they pulled in more. I think it has a lot to do with having the bait caster rigged with higher strength line which makes the bait not react the same.

David and others have a pretty comprehensive list of fishing applications. I'd add fishing spy baits if it hasn't been already been mentioned.

Conditions-wise, spinning tackle excels in heavy winds, quartering and crossing winds, too, where bait casting can be awful. Spinning reels handle light lines better and nothing is too small while bait casters typically handle heavy lines better. If you need 6 or 8 test for a technique, you need a spinning reel most of the time.

And, it excels at skipping flukes and other baits under docks almost naturally, like skipping a stone. Really good bait casters can do this but it is much trickier to learn and perfect.

Bait casters excel at pulling fish out of heavy cover really fast, casting big crankbaits, big jigs and lures, most power fishing applications.

Note that with a spinning reel, you don't reel against a pulling fish, and never against the drag. You control and fight the fish with the rod and once you gain the edge in the back and forth tug-of-war, you reel down on your line, then fight the rod tip back again, reel down to take up the line. So, this makes pulling a big LMB out of thick cover problematic. Spinning tackle wears the fish down as part of its strategy; with a bait caster, at least some of the time the angler over-powers the fish, else he'll get wrapped up and break off.

I like bait casters but greatly prefer spinning tackle because I greatly prefer finesse fishing over power fishing.
