i was recently in the same boat as the OP, having switched to baitcasting just one week ago.. the reel i have is a round baitcaster, but its smaller in size, so handles closer to a low profile and i can safely say i dont find myself going back to spinning anytime soon, i prefer baitcasters now.. casting has become second nature to me and in the last few days i went fishing the only time i got a backlash was when i completely shanked a cast, throwing my lure into the mud in front of me (i was casting off-handed).. other than that theyre smoother, more comfortable, i feel i have more control over the entire rod/reel/lure and they even look cooler
unfortunately, i purchased this locally where all they had in stock was right hand retrieve models.. i dont know about you, but this seems incredibly counter intuitive to right handed people, we cast with our right hands, it seems like a waste of time to swap hands just to reel, especially if youre lure fishing and doing a lot of cast, retrieve, cast, etc... when i fish shallow areas with a crankbait or a spoon my lure ends up in the mud or weeds in the short period of time it takes me to switch hands. many, if not most of us coming from spinning have the crank on the left side for this reason, so if youre coming from this setup, trust me you will have a harder time getting used to swapping hands and reeling than you will getting used to casting and handling the reel... but just about everyone makes left side retrieve model baitcasters now anyway, and if this is how you reel, dont settle for buying local if you can only get a right side model
