Don't want to make things complicated but your selection may depend on what you are going to use the reel for and your maintinence habits. Gear ratio and Inches Per Turn (basically speed) can relate to which species you are targeting and what lures you use. Maintenance will determine how long the reel lasts.
For bruisers and slower fish, I use a slower reel. A slow reel allows you to winch in a large fish and also allow a slower fish to hit your bait. Lures like spoons and crank baits are best used on slower reels.
Fast reels are best for jigging for fast pelagics, horsing fish away from structure with a large power handle, or fish that can quickly close on you. If you use ball n feather, a fast reel is preferred.
As for maintenance, most reel frames are made of metal (including aluminum), and/or some sort of formed material like graphite composite. I prefer a reel that doesn't flex and aluminum is more rigid than most graphite composites BUT if I'm fishing the surf or somewhere that salt water is going to get into the reel, I'd prefer a graphite composite reel because it doesn't rust. Otherwise, my OCD side would be cleaning the salt out of an aluminum reel every time I fished the surf with it.
ABU low pros can take in water from cast mist after hours of casting. Their MAX series reels have some of the most rigid graphite composite frames. Lews reels are very similar but less water gets in. Daiwa bearings tend to rust easy.
If I were to pay a $100, the Lews Speed Spool LFS looks good. It has an aluminum frame. I liked the old Lazer. The new one flexes.
I know nothing of the new Shimano offerings but they have that SLX for $100. I couldn't figure out what it's made of though.
If you're looking for a graphite framed reel go with the ABU MAX series. I own a Pro MAX but the Black MAX works good, as a couple of my friends own them.
As for Daiwa, I don't own any any newer reels that are $100 or less. Just bought a fast 8:1 gear ratio reel though.
There are other brands but I don't know how well they stand up in the salt.
