The Chicago is made in Taiwan, but that's not a bad thing. The Chicago's blade in CTS-BD1 which is a decent steel. The Squeak's blade is Bohler N690, a slightly tweaked equivalent equivalent to VG-10, and a bit better steel than BD1.
The Chicago, being a liner lock on standoffs, has flow through construction so you can clean it out very easily. That said, my corrosive sweat and the liners on the Chicago not being polished to mitigate corrosion lead mine to develop rust on the scale side of the liners. But that was 4 years ago, and Spyderco may have started polishing the liners since then to prevent this.
If your work will allow you to have a 2.4" blade with 2" cutting edge, then I'd recommend the Blade HQ G10 scale CRKT Pilar over either Spyderco, even though it has a lesser blade steel than those two, because it's a frame lock without liners. The Boker Plus Subcom is another high quality 2" blade frame lock without liners, but the handle is tall top to bottom and the jimping all around is aggressive, so it's not the most comfortable knife to carry.
Really it comes down to your needs and wants though. How important are corrosion resistance, edge retention, ease of clean out, and a locking blade to you? What's your max budget?
