Trust me it REALLY depends on the box and the coaches...there's 2 coaches that aren't super helpful, but they're still nice and friendly, but the owner, and 2 of the other coaches are amazing.
At 515, you can't do a ton, so they walked me through modifications, they give me extra help to get better form, they slow me down when I want to push past my limit or feel I'm not progressing fast enough -- so I don't get injured.
Heck, they even call and fb chat w/ me if I miss a class. I started 9/10 @ 515. It's 12/27 and I'm 430. Goal is be <300 by 2020 (40th birthday).
I can see CrossFit REALLY sucking if quality isn't there, and the coaches suck, I don't like going to classes AS much when the good coaches aren't coaching, so I think that's the difference..
A normal gym you just have equipment, quality doesn't matter that much, in CrossFit --it's all about the people running the place, if they aren't attentive to those who might need extra help getting up to par, then find a different box.
