Multi-tools and torque wrenches
A tool for the ride, or a tool for the bolt?
These are not competitors and the score at the top of this page does not settle anything. One lives in a saddlebag and turns any bolt roughly. The other lives on a bench and turns one bolt exactly.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.
The tool that goes with you. Two to six millimeters is almost every fastener on a modern bike, at 205 g (7.2 oz) in a 90 mm (3.54 in) package — and it is the best-selling tool in this hub. It cannot tell you when to stop turning, which is exactly what a carbon bolt requires.
The tool for carbon. An audible and tactile click at 2.5 to 25 Nm means a stem bolt you cannot see is still set correctly, and 5 Nm sits comfortably inside that range rather than at its edge. It is a bench tool and it is not going in a jersey pocket.
Most people who own carbon parts do, and they are not substitutes. The multi-tool handles a roadside adjustment; the torque wrench sets anything with a printed figure on it — carbon bars, stems and seatposts almost always have one.
Printed on the component next to the bolt on most carbon parts, and in the manufacturer's manual otherwise. Use the figure on your own part; nothing on this site derives one.
For almost everything on a modern bike: stem, seat clamp, bottle cages, brake and derailleur bolts. The 8 mm (0.31 in) size some crank bolts need is not a roadside job in any case. Check whether your rotors need Torx before treating either tool as complete.
