I'll admit they have their place, but I'm not a fan of multi-tools. I also think that the more functions they yave, the less useful they become because it gets so awkward to orient the tool to do what you need. Tightening a water bottle cage, for example, is often impossible with a multi-tool.

Somewhere I have a Park mini-chainbreaker that I sometimes carry with me on rides. I like them better than the ones on mini-tools but, last time that I tried to use one, I wound up taking a 4 mile hike-a-bike because the removable pin had disappeared.
