Bud, I've used them interchangeably for years. Never really gave a lot of thought to it, as long as the line did what I needed and was affordable. The other choice for me has been braids.
I've used Ande mono lines a long time off & on, and have gone back to using them. Also still use the Yozuri Hybrid. Stretch and memory have been my primary considerations, plus cost, and they each vary between them, but both have worked well for me. We all view the lines we use differently, because of how we like to fish.
I used Silver Thread too in the past, mainly in light tests for, 4 to 8 lb, for panfishing and general fishing, and have no complaints about it, except when they started making the AN version, I didn't like it as much, because it had more memory IMO than the earlier line they made. I also only used it on spinning gear. I use the Ande & Hybrid on both spinning & casting gear, and some just do not seem to work well on both. Yozuri makes a "soft" version that does work well on spinning gear.
I've used the various popular lines like Trilene & Stren too and they have varied over the years. I can't say I had any bad experience with them, but also wasn't looking for line that worked well for any specific techniques. These were more general purpose. Big Game was one of the Trilene lines I used for bass, and it worked, but has a good bit of memory. I still have a surf fishing reel with Big Game on it, only because it's not a costly line and when all I'm doing with it is dunking bait occasionally, don't see a need for specialized line.
IMO, some of these lines change, because the brand changes who actually produces them, so now that's a consideration for me. It wasn't in the past. I've been buying the Ande line direct from them, and it's the same line as I used 30 or more years ago as near as I can tell, so now to me that's important. So far the Yozuri line has also been consistent, and I like it a lot, so I've been sticking with it.
I've yet to find perfection with any line, and there may be better choices, but I'm going to stay with what I've been using as a good balance of performance & cost.
