Thanks for your replies. Interesting points.
However, i kept the Victorinox.
My very subjective reasons:
The Swiss is built like a tank spare part. The Surge, while somewhat better in hand, had a bit of play and did open too lightly but not smooth.
Some reviews mention this so i don't think i got a dud.
This might not be technically true but psychologically, i want the tool that comes as close as possible to a professional, super safe, solid steel object.
The Swiss tool might serve as hammer if needed.
Leatherman Surge, more expensive than the Victorinox Swiss Tool Plus (wrench edition now available at around 80 EUR), lacked this feeling.
At a initial look, i was all pro Leatherman for the bitholder being part of the tool. But now I'm not sure if using it on a couple really tight bolts will weaken it's construction even more. At product shots, i often have to remove parts of object, that were meant to sit there forever. Not to mention working with hex bolts on larger stands and tripods.
The compact external wrench in the pouch makes sense and i'm going to replace the decent included bits with top quality ones.
If you're the carbon guy, the Surge (compared to the ST with pouch) is lighter and seems plenty sturdy enough
The scissors on the leatherman are a tad larger but as expected, no replacement for real, solid scissors.
