All three are good reels.
The Tyrnos has a rebate on them from Shimano -- that's an indicator that they want to clear out stock. I have a very strong suspicion that Shimano will debut a new small metal framed lever drag reel at ICAST in two weeks. What I'm telling you is that there are going to be some killer deals out there on Tyrnos reels.
The Torium is an excellent reel as well - just a star drag. For bottom fishing, that is preferrable IMO. The problem with the ARB failing usually occurs when livebait fishing for large fish who "hit on the go", like tuna. Guys freeline the live bait and when the fish hits, throw the reel into gear, engaging the drag. When you have 65lbs braid on a Torium/Trinidad/Saltist with the drag at 15lbs or more; and you'll get failures.
The TLD is good solid reel for many purposes -- but it's weakest at bottom fishing. Oh, it'll work just fine, it's just not as good for grouper/AJs as it its for Sailfish/Kingfish/... and general trolling.
For the $$, I'd get that Tyrnos 16, spool it 50 or 65lbs braid and a 50-100yds mono topshot. It's metal framed (stronger than a TLD), topless (great for drifting livebait back in the spread), and a smooth drag.
