Well, I can't really say that since I've not tried the Varia, but this Zefal Spy mirror is something I can't live without. Excellent situational awareness, I never get surprised by any vehicle approaching from the rear.
Video is a bit wobbly, but in reality it's much more stable than that.
Can swap between bikes in seconds (although I own a couple of mirrors).
I can see behind me on all 3 hand positions. In a steady stream of traffic I can anticipate cars vs buses vs trucks etc - not sure what the Varia would do better.
Although it's better with 44cm bars rather than narrower ones, as you'll see more of your hip/thigh.
Can't recommend these highly enough, used them in the US and Europe. Never tried to fit one on my TT bike though.
