My very favorite is the Park MT-1. I have one for road, one for mountain, and one I often wear as a necklace. There's no chain tool on that model of multi-tool...and frankly, in 30+ years of riding on the road, I have never ever needed to fix a chain. 

I suppose if I were adventure biking or way off in the backcountry on my mountain bike, I'd probably bring a tool with a pin pusher. I like the Topeak Hexus X for that purpose.
