This probably wont be any help to the OP, but its all about the drags. I fish for salmon but not musky so that is my experience. Mostly downrigger, but I do have dipsy gear, just don’t use it much. I have one LC, most are just LW of pure conventional (non-LW). I have a convector that I don’t really like. It was smooth in the store, but I have had it randomly free spool. I have taken it apart, cleaned and lubed it right, and it all looks fine, but something in its design cause it to do that very randomly. So its on the 4th line in my set. I don’t have any high end reels and my collection starts with an old Daiwa that was my first salmon reel bought about 30 years ago or more. Its plastic body LW. It was “OK” but started to get weird with the drag where the drag would hold hold hold then release in huge zing, then hold hold hold. Started to lose fish so the reel was put on the 4th line or actually down to the farm team. Then about 10 years ago, I saw an HT100 carbon fibre drag washer set on eBay so bought it. That new drag fix put that reel back on the bench (2nd line though).
Believe it or not my most reliable and smooth workhorse is a Penn 209 LW that I have also upgraded the drag to HT100 carbon fibre. That reel is steel framed, pretty darn smooth for an old bugger and the drag is reliable and smooth. I also have two other old Penns that are pure conventional (one is a Del Mar) with upgraded drags and they are great. Smooth and drags are nice. They are my backups.
I also bought a Kastking LC on Amazon two years ago. I have to say its pretty good. If I am running two rods its one of them. Its too early to say if it will hold up, but for now its caught a lot of salmon. It has a pretty fast retrieve too, so sometimes that has an advantage when I have a salmon that is charging the boat. It has HT100 carbon fibre drag washers. (Yeah Yeah, Chinese crap that may not be able to get parts for. I get it. I think its better built than most Chinese reels though.)
I also bought a saltwater conventional non-LW star drag reel (a Fin-Nor 20) that my idea was to use it for trips south as well as maybe try it on musky or salmon. Its pretty big though. Not too heavy. I picked it because you can cast with it too. Its super smooth and casts a mile with heavy lures, and can be used for trolling too. The drag stack is huge and smooth. Its designed for much bigger fish than even our larger salmon or musky. I haven’t used it for actual fishing yet though. Just playing around at the cottage. I loaded it with 60lb braid for Florida bottom fishing and then didn’t do that trip so its not really set up for downrigger fishing up here.
Anyway, probably not much help. But for me, its all about the drag smoothness IMO and I think cheap plastic may flex too much to allow the drag stack to be smooth.
