Some anglers are a little put off by the difficulties encountered when using baitcasting reels.
I use a baitcaster about 60% of the time and LOVE it! Granted, it's a pretty expensive reel that a couple family members went together on and gave me as a Christmas gift. Recently, I bought a cheaper baitcaster and was less enchanted. None the less, a baitcaster is better when you want to use heavy line, certain applications, or big fish are expected. More importantly, the accuracy achieved with a baitcaster is incredible!
