I've tried to like Wenger as much as I do Vic, but I really think Vic is better.
1. Wenger springs tend to be weak compared to Vic. All of the Wengers I have do not have that nice snap.
2. The Wenger combo tool ( found on the Evo 63 and Picnic) sucks compared to the Victorinox. Hard to open cans with and the screwdriving portion is very close to the angled can/bottle opening portion which could make it hard to turn in certain situations.
3. The Wenger toothpick is flimsy and small compared to the Vic's.
I do like the Wenger scissors and bottle opener/ screwdriver that locks when you push on it.
Also the Wenger Standard Issue is their best knife, in my opinion.
That said you should add a few to your collection. They tend to go cheaper than Vics on Ebay, especially used models.
