One of the issues you may find is a different tire brands spec their widths differently. One may claim 26 mm when it’s actually more like 28 when pumped up.

nobody’s gonna be able to tell you if it’s going to be worth it I will tell you that I went from 23 mm max PSI to 28 mm lower psi and it made a huge difference for the better. They were different tires though but on the same bike. I went from having a bike that was twitchy and on the verge of being out of control going fast downhill to one that sticks to the pavement like glue
