SpecsUpdate
Pros
Pro Allows storage of attachments such as pictures, documents and all kinds of files in general
Appending attachments to individual credential entries allows things like scanning important documents (for instance a scanned document containing the login information for your internet connection), appending them to the corresponding credential entry and afterwards destroying the original paper copy.
Pro Offers multiple sync options
Since the database is stored locally it can be synced across devices using a cloud storage service like Dropbox, Google Drive or via a file sync tool like BitTorrent Sync. KeePass v2 also provides a powerful built-in synchronization mechanism that allows setting appropriate level of sync, kind of sync, and choosing between a number of sync sources (Dropbox, Drive, etc).
Pro Works inside Android apps
There are variations in support of features, so this is dependent on the Android app being used. Keepass2Android is one that has built-in synchronization over ssh and other protocols, fingerprint support and plugins are also supported to a certain extent.
Pro Customizable password records
Users may define any extra fields (eg. "Surname", "Credit Card No", "Start Date", "Expiry Date" and "Security No") and their values may then be easily copy-and-pasted when required. This is a great feature not found in a lot of password-managers: they leave you to consign such additional information to the "Notes" section.
Pro Extensive plugin and extension support
Keepass offers a range of plugins and extensions in different categories: Integration & Transfer, Automation & Scripting, Cryptography & Key Providers, and others.
Cons
Con Officially supported only on Windows, Mono or Wine
While there are ports available for Linux, OSX, iOS, Windows Phone and Android, the only officially supported version of KeePass 2 is on Windows and all platforms running Mono like Linux, Mac OS X, BSD. KeePass 1 is supported on Windows and Wine.
Con Uses a database
As it uses a database and doesn't handle everything as a file it will decrypt all passwords every time. Instead of just opening the single file it will open the database containing all passwords.
