I don't think the ORM concern is valid - SQLAlchemy is probably the best ORM available for python and you can drop it straight in to your flask app.

As you say, it really depends on your use-case. I wrote a number of crud apps in Django in a previous life (when Django was still fairly young). I found that out of the box you could get something set up quickly but trying to bend it to your (or the clients) will sometimes required a lot of work. I remember at one point having to duplicate a huge chunk of code into one of my models. That's the tradeoff you'll always run into. You'll get a really complete system for free but it won't be as flexible as you may one day need it to be.

Agreed on both counts. (I don't use SQLAlchemy nearly as much as I should, and I'm often reminded of that fact.)
