Well..., here's my 2 cents...
Having carried the Compact for a couple of months a few years back, i feel it's a great for someone wanting a pocket knife with scissors, but completely sub-par for someone wanting a multi tool.
The combo tool sucks for most of the usability i get from the Bottle and Can opener tools, also miss the small blade and awl. I use it sometimes at home, but i don't have it on the EDC rotation anymore.
In a comparable way, i think the Compact is every bit as overrated as the Explorer for me... I'd take a Climber over them any day. If i'm going 4 layers, i'd go with the Deluxe Tinker any day
