Wiha or Icon pliers?
I own some of both.
It really depends on the end use. They are not one in the same regarding application.
Icon are targeted for automotive repair and grease monkeys, just like Snap-on.
For instance, you're not getting an Icon linemans, but they do have the 3 position slip joints.
Grips are only available in one style, the nonslip cushion.
IMO, the line is quite limited in overall selection.
Wiha, are designed largely for tradesmen, craft-technicians, precision electronics, and mechanical installers.
They offer a much wider selection of features for those targeted professionals.
For instance, the circlip pliers have a unique profile called Magictip that aids in retention. (The Icon circlip pliers are pretty lackluster, IMO.)
The high leverage BiCuts are another unique tool and work very well.
Even their basic pliers have some subtle additions like the exterior crosshatch on the linemans.
Grip options are standard dipped, two component, high voltage insulated, or ESD.
Wiha's pliers range is much more extensive in sizes, patterns, and finishes.
With all that said, I do wish they still made pliers in Switzerland and Germany.
Pliers are much like screwdrivers when it comes to ergonomics. They are rarely one size fits all. I don't really care for Snap-on or Icon plier design. They are too straight and wide for my preference and end up being uncomfortable with extended use. I find the Wiha profile to be more comfortable in my hand, especially the two component grips. But then you have to consider, these probably wouldn't fare well in an automotive environment.
I try to be open-minded when making tool choices and I often find that the popular opinions here are not always the best for me personally.
