I would give the Topos a try. I've had two pairs of Trailventure 2 (and several pairs of Altras) and have found them to be similar in width to Altras. I think Altra are slightly longer in length especially the Lone Peaks. As mentioned previously by other posters - you really need to try them on. In my experience the Topos are a bit more rigid than the Altras, which I find more reassuring in use. As with all hiking gear decisions, it depends on what fits you best and what makes you feel good on the trail!
Both those shoes are much higher stack and I would not recommend either for technical terrain. MTN Racer 3 *could* be a good option if you can get a good midfoot lockdown, but it lacks in that department in my opinion. But its stack is still fairly high, and you lose a ton of ground feel vs Terraventure. Not sure about the new 4 version. Vista’s stack is much too high to ever be considered suitable for technical terrain. I know of the terrain you are referring to in the NE and I would not recommend either for it, personally.
Topo Terraventure’s are 3mm, MTN Racer’s 5mm. Both are wider than average, though perhaps not quite as wide as some other models or other Altra models. They also have a snugger fit in the midfoot, which I personally like. I’ve found it’s much easier to get a good lockdown fit with Topo while still having plenty of room to move my toes.
I really should’ve mentioned I’ve tried the Terraventure WP and it reflects the issues the reviewers have. It’s pretty tight at the knuckle of the feet to the toes.
Terraventure is bombproof I wore out the upper before the tread wore slick. I've gone through 5 pairs in the last 4 years. And I do a lot of 4th and low 5th class scrambling in them in addition to long runs. I will always chime in to confirm when someone mentions the Terraventure here.

Versatile road-to-trail, but struggles on wet, technical downhills.
