Admin Interfaces for Rails Apps: RailsAdmin vs ActiveAdmin

If you are rapidly developing a prototype it's different, but IMHO you should replace these components before the refactor becomes too much of a bugbear.
I find prototyping plenty fast with vanilla Rails, a few backend plugins, and Twitter Bootstrap. And on the far end of the scale, my experience is that larger projects require an amount of customization that does not easily fit into the auto-admin paradigm.
Hobo is not an admin interface. It basically is a system to enable smart re-use of components that's tightly integrated into your entire stack.
For instance, in Hobo you can type `<input/>` and Hobo will do the right thing automatically: plop down a text input if the current context is a string, a fully filled out select box if it's a belongs_to or a datepicker if it's a date. The name and default value of that input will also be automatically and correctly inserted.
Change the definition of `<input for="Date"/>` and you can change the options on your datepicker or switch datepickers everywhere or just on that page or that section.
Beginners love Hobo because they can get an app up quick. Experts love it because you can package all of your components up in DRYML and dramatically reduce the number of lines of code in your program. Where Hobo has trouble is in the middle: until you're comfortable with DRYML you're stuck with the components that come with Hobo.
Yes, I'm less interested in quick scaffolding, be it via code generation or ready components, but clean reusable view components does sound appealing.
Rails helpers are great for some things but more complex cases like custom form builders can get ugly (no, formtastic is not always the answer). Will give Hobo a look next time.
I found working with ActiveAdmin to be very straightforward, and it sounds like getting the equivalent of RailsAdmin up and running may take an extra 30 minutes.
The big win after those 30 minutes is that you have a flexible admin module that you can continue to tweak / improve where necessary.
ActiveAdmin feels like the solution with the smallest chance of painting yourself into a corner and therefore seems like the best recommendation of the both.
Even if you would have to invest 2 extra days into ActiveAdmin compared to RailsAdmin, I'd say the flexibility is definitely worth it.
Bonus tip: ActiveAdmin is in heavy development, and the documentation tends to lag behind a bit. I've found the github issues for the project to be a great source of information though.
Disclaimer: I'm one of the maintainers of Hobo. But I got into that position after I fell in love with it.
Hobo isn't primarily an admin interface, it's designed for rapid development of CRUD+state machine apps. In essence you start your app with an "admin" style interface and iterate until you get your full app. You can of course also add an additional scoped admin interface.
I can only reason that the author has never spent more than a few minutes with django's admin.
Last version of Typus is fully compatible with Rails 3.1 and there are also branches compatibles with Rails 2.3 and 3.0, MIT-License, bla bla bla ...

It just isn't actively maintained by multiple people and marketed like the other two are. They haven't even bothered to write a description on GitHub that would appear in the news feed of everyone following a GitHub user who watches it. I got an error when I tried to visit the website.
Edit: I added an issue asking about adding a description.
