If you want a traditional adjustable wrench, the best version is the Channellock-branded Irega. You might be able to spend a lot more for something similar, but you certainly won't find anything comparable in the same ballpark (i.e. I bet you could budget 3x as much and not get a better adjustable).
However, the Knipex pliers wrench is a game-changer. Don't dismiss it just because of the price. It's useful for way more things than a regular adjustable wrench - albeit the utility is hard to explain until you use one. It's not the same as smooth-jaw pliers from Irwin or Channellock.
The clamping force means you can grab onto mangled fasteners, squish/squeeze things together, use them to hold things while you work (say at a bench grinder)... You can "ratchet" them for repetitive turning. Precisely bend things back into shape (ever mangled a key? Put it in your pliers wrench and squeeze).
You mentioned:
The only con is that it requires a squeezing force in order to use it
Keep in mind most of the squeezing force happens when you pull on the wrench to turn the fastener. It's not like a pair of pliers where you have to be squeezing hard to ensure nothing slips. The pliers wrench multiples your squeezing force so you really don't have to squeeze that hard.
If there's space, I'd often sooner use the pliers wrench over the open end of a combination wrench - you certainly can't say that about an adjustable wrench. Think about that - if the reason you wanted an adjustable was because you weren't sure what size combination wrench to grab, didn't want to carry a handful or the length of a combination wrench isn't needed, the pliers wrench not only serves the same function but actually offers advantages over the "proper" tool.
If it's just too expensive, consider the WIha version. Taiwan-made I think, versus the German Knipex, but it is also a good tool and should be available cheaper. Irwin makes one too, but I don't think it is as good. There's also a weird Lenox version intended for plumbing.
You might be able to tell, like any recent religious convert, I'm eager to evangelize the pliers wrench. I'll keep going if I have to.
