I really prefer wenger's tweezers, scissors and main blade, and I love evogrip, but I just cannot use the can opener. Also no alox range! That's why they're 2nd best for me.
Quality-wise, I've seen differences in the past but we're talking about the difference between Victorinox's A+ and Wengers A-, it's not a serious thing, only if you compare directly with Vic. And I'm willing to believe they've addressed that now.
