If you want a dedicated tool for touring, CT-5 is good. I always had reasonable luck using the chain breaker on my Crankbrothers M18 until I started working as a mechanic, and think most people are fine with a multitool chain breaker assuming its compatible with the chain they use (a lot of them aren't really designed for 11 and 12 speed, though this is changing, my Park IB-3 will do 12 speed except AXS). Pro shop tools are about durability over hundreds to thousands of uses and small optimizations of speed. I need to break a chain on my personal bikes--what, maybe annually?
