I used spinning reels only until about a year ago, and now I prefer using a baitcaster when I can. It's definitely better for working moving baits because the reel handle isn't so far from the rod--using a spinning rod for cranks or jerks just feels awkward to me now. I use spinning gear for really small swimbaits, tubes, and dropshotting. For senkos, I use either.
So, I'm glad I gave it a try, it really changed things for me.
