While both Tor Browser for Android and Orbot are great, they serve different purposes.
Tor Browser for Android is like the desktop Tor Browser, but on your mobile device. It is a one stop browser that uses the Tor network and tries to be as anonymous as possible.
Orbot on the other hand is a proxy that will enable you to send the data from your other applications (E-Mail clients, instant messaging apps, etc.) through the Tor network; a version of Orbot is also inside of Tor Browser for Android, and is what enables it to connect to the Tor network.
That version, however, does not enable you to send other apps outside of Tor Browser for Android through it.
Depending on how you want to use the Tor network, either one or both of these could be a great option.
We recommend iOS apps Onion Browser and Orbot for a secure connection to Tor.
Onion Browser and Orbot are open source, use Tor routing, and are developed by someone who works closely with the Tor Project.
However, Apple requires browsers on iOS to use something called Webkit, which prevents Onion Browser from having the same privacy protections as Tor Browser.

All of the tracking code is disabled in Tor Browser for Android.
Additionally, a complete removal of the tracking code is planned.
