Multitools and carrying it regularly - bring different levels of enthusiasm for me. Most pliers-based tools are too heavy to pocket carry. When they're small enough not to be intrusive, they're often too small to be useful. Looking at you Dime:
However, I've got multitools in my vehicles, my office desk and usually in my bag. I have one in my gear when I go camping, kayaking or dirt biking.
It seems to me that some of the objections to multitools come from people who have regular tools nearby. If you're carrying a toolbelt, a multitool makes no sense. Use a real tool.
...but if your handlebars get knocked loose in a crash, chair seems a little wobbly, door isn't closing right, battery cable needs to be snugged up, etc., you can fix it.
If I'm going to pocket carry a multitool, I use my skeletool. It's still at least an ounce heavier than I would like, but I've yet to find a lighter tool that is as useful. I wish they'd make an ultralight version.
In my office I have a Victorinox Spirit X. It seems like the most dignified multitool. If you're going to whip out a multitool in a professional setting, this is the one you want.
My SUV and truck both have SOG Powerlocks. Admittedly, this is a heavy, old-school multitool design that requires you to open and close the outer flaps to access the fold-out tools - which is slow. However, the pliers head is excellent, the compound leverage makes a difference, the covers make it comfortable to hold, the tools lock and the whole thing is both robust and inexpensive. It's a great vehicle multitool.
I've got a bunch of SAK's too. Spartan, Rescue, Swisschamp, Camper, Huntsman, Alox SD, Bantam, Electrician Alox... might be more that I'm forgetting. I think they're amazing, high-quality tools for what you pay.
I picked up an MKM Malga too, just because of the M390 blade. It's a very nice knife, but the backspring is a little weak, the awl isn't sharp, the can cutter works - but not as well as on an SAK... I think it also highlights just how good Victorinox knives are.
