I was putting EMT in a Bell box the other day and I tried one of those offset connectors. I got lucky that in one end it lined up right with it wrench tight but if I had needed one on the other end I would have been in trouble. Made up tight without a lock nut it was about 90 degrees from laying against the wall and with a lock nut there weren't enough threads engaged to actually tighten it up. Usually I just bend an offset but I was trying something new.
Reno I am guessing you are talking about the thread to thread connector with lock nuts on both ends. These are EMT to thread. It does make a lot cleaner installation than an offset, less places for spider webs. When used with a KO and a lock nut it is easy to insure it is tight when properly aligned. When you have a threaded hub like a Bell box it gets tougher.
I've never been a fan of those offset fittings. They send up a big red "DIY" flag to me, just like factory-made EMT ells that they sell in the big box stores. A nice clean EMT job with professional bends and offsets (not just guessed where the box ends up at the end of the pipe) have always impressed me.

You say that like it's a bad thing.
We get lots of people pulling homeowner's permits, so those fittings, ells, etc. make it easier for the homeowner to do his/her own work (perfectly legal here, with a permit, and they live in the house). If it meets code, we approve it. Doesn't meet code, we don't, same as any other permit pulled by an EC.
I've been using the Greenlee Little Kicker for many years and all the offsets for 1/2" EMT fit 4x4 & 4 & 11/16 boxes perfectly. The 3/4" model is a little different and how much offset you get depends on how far you pull the handle, you can offset too much for a 4x4 box.
Few things are harder to put up with than the annoyance of a good example.
