With baitcasting reels the line runs from the rod tip directly to the spool, with a coffee grinder it rounds the bail roller before the spool so you do get less feel. If you hook the line around your index finger then it sort of makes up for it.
When fishing carolina rigs where you are in contact with the bottom then a baitcaster is the better option for more feel. Also when pitching (Texas rigs) its easier to pitch accurately using a baitcaster. Fluorocarbon can be high maintenance on coffee grinders because it tends to jump off the spool so guys use baitcasters. That said the light fluoro lines 6 - 8lb are "easier" to manage on coffee grinders. Some guys prefer braid on the spinning reels because its easier to manage than fluoro, its very direct so you have as much if not more "feel" than with fluoro. Also the new braids are super thin for their breaking strain so you get a superfine line that doesn't break.
However when it comes to finesse fishing ..... in other words drop shot, light mojo rigs, light crankbaits, light spinnerbaits and light topwater then a spinning rig is used. Thinner line and softer rod tips together with line comming off a fixed spool make it easier to cast these lures. Finesse is about downscaling, line, lure, hooks, swivels, weights etc. But you need a soft rod to compensate for the thinner line, although with the new braids there's room to start using rods with faster tips to get better hookset.
Remember bass drop shot which is essentially a straight down technique is different to rock and surf drop shot. The latter is basically the same as leadhead fishing in bass.
