Raspbian is an unofficial port of Debian Wheezy armhf with compilation settings adjusted to produce optimized "hard float" code that will run on the Raspberry Pi. This should provide significantly faster performance for applications that make heavy use of floating point arithmetic operations.

The Raspbian port is necessary because the official Debian Wheezy armhf release is compatible only with versions of the ARM architecture later than the one used on the Raspberry Pi (ARMv7-A CPUs and higher, vs the Raspberry Pi's ARMv6 CPU).

The official Debian Squeeze image issued by the Raspberry Pi Foundation uses "soft float" settings. The foundation found it necessary to use the existing Debian port for less capable ARM devices due to time and resource constraints during development of the Raspberry Pi. Therefore, it does not use of the Pi's processor's floating point hardware - reducing the Pi's performance during floating point intensive applications - or the advanced instructions of the ARMv6 CPU.

Raspbian is under active development. The intention is that Raspbian will become the leading OS of choice for all users of the Raspberry Pi, but this will take time and a lot of work to accomplish. While Raspbian is useable right now, there are many rough edges that need to be smoothed out and polished.
