Why would you base your decision on some votes by random people? And I wonder what result you think you’ll get, considering this is an Elixir forum?
Spend some time to evaluate both frameworks and pick the one you are most comfortable with.

I haven’t read the posts in any great detail but I can tell you that Elixir/Phoenix users are confident enough in their choice to use it that we are not afraid to highlight the positives of other languages/frameworks 
Personally I think Phoenix is the best web framework out there and I think the opening chapters in the Phoenix book really do an amazing job of explaining why. Check out this post:
Also see this thread:
Hope that helps, and at the end of the day, just use what makes you happy or what you think is best for your project - pretty much what I think most people in this thread are likely saying

Like I said before, the django admin can be huge time saver. On the other hand if you need to deal with concurrency or background tasks then Phoenix will be so much nicer to work with.
Also after working with Elixir and its functional nature it’s kinda tricky to go back to mutable classes. It’s really so easy to reason about your code in Elixir which helps tracking down bugs.
If you need dynamic or live-upating HTML views then Phoenix live view is also a very nice feature. Sure, it can be done with javascript + websockets, but there’s way more complexity involved!
And finally working with GraphQL is amazing in Elixir - especially in combination with subscriptions. In Django we had very bad experiences, like huge perfomance drops once the datasets reached a certain size. Absinthe (the GraphQL library for Elixir) on the other hand was very fast and stable, even with complex workloads. It also outperformed Apollo (a node.js implementation) in our tests on complex workloads (deep trees).

I’m curious too. I consistently see flask benching as one of the slowest python web frameworks, even slower than ror.

Don’t listen to me. I saw flask, thought python, and in my head was thinking about japronto.

Web browsers aren’t implemented with JavaScript - but only “scripted” with it.
The server is written in hand tweaked C trying to take advantage of modern CPUs. It relies on picohttpparser for header & chunked-encoding parsing while uvloop provides asynchronous I/O. It also tries to save up on system calls by combining writes together when possible.
Sounds like this thing is implemented in C and scripted with Python.
So any Python code it has to execute (or wait for) is only going to slow it down.
