The trinidad is a little more versatile in that it has a freespooling ratchet for live baiting situations or for ease of down rigging in that you can just run the bomb down and the bait will follow without any dramas.
I've used both and found that the saltiga drag was far superior - wasn't torqued up nearly as hard and felt like it had more in reserve and felt more micro adjustable.
They both fall to hand really nicely. The shimano is slightly bigger in diametre compared to the smaller daiwas so if you have small hands maybe the daiwa would be the go. The daiwas sit on the rod with a lower more compact profile than the 16N.
The daiwas are entirely machined from full billet whereas the shimano has side plates machined from castings so I guess arent as engineeringly perfect as the daiwas if that matters to you.
I thought jigging would be harder with the shimano due to the larger diametre spool and the higher ratio, but it still felt powerful and smooth. It felt well suited to the one lift-one turn style.
The daiwas to me felt like they had more grunt (geared and drag) in a smaller reel so are my pic
