It wasn't a good day for either Big Game or Trilene on BR forum. The complaints cited were aging, poor knot strength, and inconsistency.

You run into similar problems discussing "braid" because it means different things to different people.
There's as much technology and quality difference between generic braid made the same way for 20 years, and the Izanas-made X-braids as their is (was) between Spider Wire copolymer and Toray ExThread. On the braid side, the difference is core construction and FEP surface coatings.
You never gave us your reel model (spool). Shimano Yumeya offers a whole range of shallow spools that essentially let you dial 100-m (or 200-m) capacity with any threadline size you want to try.
This is a shallow braid spool for a large frame reel, 4000/5000-size - 1520 spool, PE#1.5, 200 m
If 2-1/2-lb to 5-lb fluoro ever gets your interest, you owe it to yourself to try ExThread.
Last decade, I found a really good copolymer from Oz to use in salt finesse. Kamikaze FirePower.
Over its use run for me, I bought 3 charges for Tica Cetus, and one charge for Hardy Exalta, until ordering from Australia became difficult in Apr '20.
By then, I had made the switch to braid, and also found ExThread.
Never lost a seatrout on 4-lb Kamikaze, but did lose an over-slot snook - made up for that with a spec/snook double
another ps on the math - calculate the trip cost - good line becomes a tiny fraction, but worth its (light) weight in gold if it scores for you - and a bane if it fails.
