My take:
-I put 67g v2 zilents in an 1800 today and they definitely feel different from v1's. Like everyone is saying, they have a big bump high up. It's not a sharp or scratchy bump like on box switches so I prefer the feel and sound of v2's over royals etc. It takes a little force to start, so you won't be accidentally pressing keys. When compared to topre I'm not sure how to explain the difference, but I like the v2's better (esp once lubed). They're snappier. With smooth high bumps it sounds like they should feel quite similar, but this isn't really the case to me. I'll be interested to see a force curve. Overall they feel solid and smooth with less wobble than v1s.
-Testing the switches without keycaps I could go past the bump without activating the key if I tried.
I cannot replicate this with keycaps on, however, where it seems to activate as soon as the bump is over even when typing slowly. So this is not an issue when typing. It is possible to double tap quickly without having to go back into the bump since the activation point is a fraction of a mm below it.
-I would recommend lubing springs and sliders on zealios/zilents as it improves the sound and feel noticeably IMO.
-I'd say these are the best silent switches available.
-I like them and got used to the initial resistance quickly, but I normally type on heavyish switches. If you preferred 62g zealios to the other weights in v1, v2's may not be for you. But if you are smooth, round, tactile person who doesn't tiptoe around the keyboard, you can't go wrong with these.
As a side note, I'd rate v2's above the Hako Royal frankenswitch which had a similar concept; strong tactility high up like a box royal, but with a rounder bump than the royal due to a thicker leaf/stem combo.
