I've heard the same as you - cheaply built and mold problems. The thing is an eyesore and just looks cheap. Sad part is the same company just got the okay to build another development on Valley Road and Bloomfield Ave. They're greasing the right palms for sure.
A shame too, because it's a prime location. If they were built better, and fit into the town's architecture better, they would be a great addition to the neighborhood.
By similar places, do you mean new construction? If so, then no, there's not much downtown, as its thankfully, mostly a protected historic district. New construction is largely centered around the Bay St area. Downtown you're looking at lots of beautiful old homes (larger just south of Bloomfield Ave, smaller just north of it) as well as some apartment buildings and garden apartments built in the 30's and 40's - usually because they knocked down some beautiful old homes to build them (hence why it's protected today).
You'll occasionally see units or sale here, part of a small, tasteful condo development right downtown built around an exisiting home:

And the new condos right off of Bloomfield Ave in Glen Ridge look really nice, both the ones behind the Starbucks, and these, north of Bloomfield Ave:
16 Edgewood Rd # TH5, Glen Ridge, NJ 07028 is For Sale - Zillow
I've also heard good things about the new Parkway lofts built into the old factory in Bloomfield:
