I’ve had the Dime, Travel Dime, and PS4 Squirt. There really isn’t much competition in this size category. I really wish that would change because this is such an easy size for carry. It can go on a key ring, in a fifth pocket, and most of the places people previously carried a Bic lighter. While the small size can be limiting, the sheer amount of utility packed into the space of these tiny tools is incredible.
The pliers on both multi-tools are decent. There are things to like about the Dime but ultimately, the Squirt is a better-built tool. The main place the Squirt falls flat is the bottle opener. If you regularly need a bottle opener and don’t want to carry a separate cap lifter then the Dime is a good choice. The Dime’s bottle opener can be a joy to use. An important limiting factor is its orientation relative to the ring attachment. (It can be awkward if you keep you plan to put it on a key ring.) The other tools on the Dime are so-so. The build quality isn’t great. The knife is pretty shabby, which is a shame because the shape is nice.
I really wish someone would make a better pliers-based multi-tool in this size class. Right now, my EDC includes a dedicated pocket knife, a small titanium cap lifter, and a Squirt.
