In term of usability: its JS injector mechanism is much faster than TM last time I checked. Not that it's a big deal for normal users, but I have a few huge global scripts that I can see very visible impact.
And it's more "cleaner" as that you can clearly see each scripts you loaded in devtool and debug them, but and I think TM is catching up in this regard.
Outside that, VM is totally open source, development seems to be much quicker (with the drawback of slightly less stability, I'd admit), devs are more responsive.
