Select from OctoberCMS, AsgardCMS or Lavalite?

Hello, Gurus,

I am looking to build a web app, in which I can upload phone numbers, text messages, pictures, audio files to the website, save them, organize them and distribute these contents to phones through https request from a phone app. The phone app may also send some responses back to the web app. The web app will collect the responses, save them, organize them and display them when checking from the backend. This will be a private website and only allow authenticated users.

After some research I decided to choose one from the following three as starting point: OctoberCMS, AsgardCMS, Lavalite. Could you please share with me your recommendation on this? Which one do you think suits better in this situation? I am new to laravel. Starting with a right choice will save a lot of headache down the road. I need the one that can do the above mentioned jobs well, but keep it the simplest at the same time.

Please share your thoughts and thank you in advance.
