I just bought a pair of e-336 a week or so ago, and have 2 more pars of blue handled pliers on the way.
I hear nothing but good about Knipex and have no reason to argue otherwise, but channellock has been good to me and the price is right.
If I couldn't get Channellock anymore I'd go with Wilde, they have served me just as well are priced comparably plus seem to be finished a bit more nicely.
Not an important factor for me but appreciated when I do buy a Wilde tool.
