Pros

Since it is already installed by default, you don't need to worry about finding and installing another terminal.
Pro Light on System Resources
Terminal.app lighter uses less system resources than iTerm having the same number of windows, tabs and processes going on.

Pro Beautiful
Terminal has nice colors and font options.
Pro Window tiling
Very elegant keyboard shortcuts for creating and navigating between tiled terminals within each tab with no appreciable lag.
Pro Extensible Kitten framework
Supports plugins to add features one at a time for those who need them. Examples include Unicode input and side-by-side diffs.
Pro Tabs for multiple instances
Operate several terminals from one window using the tabs feature, allowing you to make simultaneous connections to different remote hosts.
Pro Scrollback buffer viewer
Allows for viewing the scrollback buffer in an external pager of your choice ('less' by default, with support for 'more' and 'most'), a huge benefit for turning actions taken in a live terminal session into a script for efficiency or dissemination or collaborating on workflows.
Pro Controlled and configured from the shell prompt within the program itself
No graphical menus to clutter the screen saves system resources and time once you learn that all those options are still available from the command line within the app.
Cons
Con Updates are released rarely
Terminal usually gets an update when any new MacOS version is released, which is every couple of years.
Con Tab names are volatile
The tab names never stick -- it's imperative that this should work.
Con Background images are stretched rather than clipped
Con Occasionally crashes
Working remotely with a full buffer may cause complete terminal app crash.
