DistroWatch published a review on Debian 11 Bullseye.

Debian 11 "Bullseye"

Debian 11 provides packages for GNOME 3.38, KDE Plasma 5.20, MATE 1.24, and Xfce 4.16, plus an array of other lightweight desktops and window managers. These graphical interfaces can be run on a wide range of CPU architectures, including x86_64, i686, ppc64el, s390x, armel, armhf, arm64, mipsel, and mips64el. The project's release notes go into greater detail about what is available for each platform.

Debian media is available in many flavours. There are a number of network install, CD-sized ISO files along with full-sized DVD media. There are also official live media ISOs. By default, Debian does not include non-free packages, including popular firmware, on its media. This means Debian will not work with many brands of wireless cards, preventing wi-fi connections from working. People who need non-free firmware can use unofficial media. The full sized official DVD install media is 3.7GB. I also downloaded the GNOME edition of the official live media (2.5GB) and the non-free, unofficial GNOME live disc (3.2GB).
