In terms of the choices they're unsure about; I'd say it's best to stay away from Celery / RabbitMQ if you don't really need it. For us just using RQ (Redis backed queue) has been a lot less hassle. Obviously it's all going to depend on your scale, but it's a lot simpler.

RE the sqlalchemy concern; you do need to decide on where your transactions are going to be managed from and have a strict rule about not allow functions to commit / rollback themselves. Personally I think that sqla is a great tool, it saves a lot of boilerplate code (and data modelling and migrations are a breeze).

But overall the sentiments in this article resonate with my experience.
