I've been a Laravel guy mostly, but tried Flask for a project last year, and it was so incredibly easy to get up and running.
Still not really sure how the two compare, but there was just something about the extremely tried and battletested code. Nothing got in my way, the code told you what it did, it was fast etc.
Flask is the hard one to get up and running alternative, where you must look at every detail, that lets you create an application exactly as weird as you need.
The fact that you found it so simple coming from another framework speaks loudly about your previous one. But they do compare in that Django is the easy one to start where most choices are already done for you.
