If you want something better and brand name, you'll pay more. Sometimes, significantly more.
It still doesn't make sense to use lead acid for off grid, deep cycle or not. UPS systems still use them because lead acid loves to stay charged at 100% and not drop below half, which is fine for UPS that are intended to run only during occasional power failures.
LFP batteries also last for thousands of cycles and are safe, probably safer than lead acid.
