Works with any Git remote, not just GitHub.
Clones to device letting you work offline and push when convenient.
Extends your other applications with iOS 8 app extensions.
The "free" version is not very useful if you can't do a push and $15.99 seems way overpriced for basic functionality. Limiting the amount of manageable repositories to 2-3 could be a solution here.
CodeHub is almost at feature parity with Github.com itself as it supports the most major and widely used feature of GitHub. It has full support for issues, pull requests, notifications and repository management.
CodeHub is an open source project hosted on GitHub itself. As such, it's driven by the feedback from users themselves and is constantly under change and improvements.
CodeHub is mostly free, but for push notifications and for GitHub Enterprise support users need to purchase these features for $1.99 and $0.99 respectively.

Repository overview is perfect for mobile phones and for what iOctocat is built for, easy access on the go for repos. It displays the description, a quick way to open detailed info, and a quick way for bookmarking for later.
iOctocat is at feature parity with github.com when it comes to managing issues. You can view & open all open/closed issues, search issues, filter issues, open new issues, edit old issues including all the meta data, and comment on issues.

Private repositories and notifications require the Basic update. Receiving push notifications and support for GitHub enterprise require the Pro upgrade.
