Currently, MX-16.1, mostly on 32 bit netbook since loss of internet at home due to theft of phone cables.
Today, while connected from a friend's house, I started a search on DistroWatch, using my criteria for a desirable Xfce distro, which, not surprisingly, returned the following 5 top choices:
1. Linux Mint (1) : last actively used Xubuntu about 2011.The following distributions match your criteria (sorted by popularity):
1. Linux Mint (1)
Linux Mint is an Ubuntu-based distribution whose goal is to provide a more complete out-of-the-box experience by including browser plugins, support for DVD playback, Java and other components. It also adds a custom desktop and menus, several unique configuration tools, and a web-based package installation interface. Linux Mint is compatible with Ubuntu software repositories.
2. antiX (22) : IceWM was my favorite for several years, replaced by Xfce4.2. antiX (22)
antiX is a fast, lightweight and easy-to-install Linux live CD distribution based on Debian's "Stable" branch for x86 compatible systems. antiX offers users the "antiX Magic" in an environment suitable for old computers. The goal of antiX is to provide a light, but fully functional and flexible free operating system for both newcomers and experienced users of Linux. It should run on most computers, ranging from 256 MB old PIII systems with pre-configured swap to the latest powerful boxes. 256 MB RAM is recommended minimum for antiX. The installer needs minimum 2.7 GB hard disk size. antiX can also be used as a fast-booting rescue CD. A special Xfce edition made in collaboration with the MEPIS Community called "MX" is also available.
3. MX Linux (23) : Discovered a few days after the release of MX-14. In daily use since 02-Apr-2014. Note: MX Linux uses SystemV init plus systemd-shim for compatibility. It doesn't actually use systemd.3. MX Linux (23)
MX Linux, a desktop-oriented Linux distribution based on Debian's "stable" branch, is a cooperative venture between the antiX and former MEPIS Linux communities. Using Xfce as the default desktop, it is a mid-weight operating system designed to combine an elegant and efficient desktop with simple configuration, high stability, solid performance and medium-sized footprint.
4. Refracta (196) : Currently Devuan based. The original, based on Debian, provided some code and the inspiration for the incredible MX-Snapshot.4. Refracta (196)
Refracta is a Linux distribution based on Devuan GNU+Linux (a systemd-free fork of Debian), designed primarily for home computer users and also for use as a system rescue and recovery disk. It provides a simple and familiar layout using the Xfce desktop. Other desktop environments and additional software packages are available from the Devuan package repository. Besides providing a Linux distribution on a live CD, the project also develops useful tools, such as refractainstaller, refractasnapshot and refracta2usb which allow users to customize the installation and create custom live CD or live USB images.
5. Star (300) : Devuan based. Devuan still developing as a fork from Debian without systemd.5. Star (300)
Star is a desktop-oriented Linux distribution based on Devuan GNU/Linux. Star is available in a range of editions, each featuring a lightweight desktop environment. Star is small enough to fit on a CD and uses SysV init software.
