I actually rank Verizon ahead of both the Hub Residential and the Avalon tower in the NS cluster. I think a big part of that is that it was originally supposed to be around 400', with the residential well over 600'. This one ended up improving while the residential is among my biggest disappointments. The residential was supposed to be the area's peak, but now the area has no peak. It looks like 4 buildings of essentially the same height.
Overall ranking of new addition to the main skyline, spanning Government Center through North Station:
1: State Street Tower (expected) - Obviously not up yet, but I suspect this one will challenge MT, 1 Dalton, and potentially the Aquarium Tower if it happens, for best building out of the entire boom. It's the peak that legitimizes the area as a true extension of the financial district skyline. Also, I typically favor office buildings over other uses from an aesthetic standpoint, and it's been a while since we got a really good office tower like this.
2: The Sudbury - Classy, high quality materials, less bulky than expected, plays well with its neighbors. I love this one and am sad to see it disappear from the North so soon, although not THAT sad since it's SST replacing it.
3: The Alcott - Classy/classical look, glassy, bright. I like it a lot, but think the materials on The Sudbury (plus the extra height at a crowded level of the plateau) put this one behind the Congress Street Garage pair.
4: Verizon - I like the powerful, neo-industrial look, and the base section also looks great. The blob glass above the base is the worst part. Materials are good. Kind of looks like it belongs in Tokyo. Also, I'll take a surprise 500'+ building any day, every day.
5: Hub Residential - Very disappointing compared to what might/should have been from a height perspective. For what it is, glass looks OK, pattern is unique for the city, and the thin side from Government Center actually looks pretty great.
6. Avalon - I actually was perfectly satisfied with this one when it was first built. However, in context with the surrounding towers it's the shortest and blobbiest, with the worst materials. It kind of looks like a mess compared to the rest of them, but at least it adds to the density and set a new precedent for height in the neighborhood.
