1. Ubuntu

• Easy to use
• Unique user experience
• Huge collection of software applications available through the software center Essential tools pre-installed
• Good community Forums

The most popular & well-heard Linux distro is the open-source OS Ubuntu. Maximum new users who are switching to Linux OS try Ubuntu due to its ease of use, user friendly interface, large community, wide range of software & lastly, all the free features.
By default, Ubuntu uses the GNOME. It takes some learning if all you've known before is Windows, but it's really not that hard. Once you get accustomed to the interface, you'll see that it makes perfect sense (and you might even wonder why other desktop operating systems don't follow suit).

2. Linux Mint

• Easy to use
• Familiar user interface with Windows
• Better for performance on older hardware
• Improvements over ubutnu

Tired of Windows? Then consider turning to Linux Mint, in particular, the version using the Cinnamon interface. I'm a Linux power user, I can highly recommend it to anyone, even beginners.
Mint, with several desktop environments such as Cinnamon, looks a lot like XP or Windows 7. It uses a Windows Icon, Menu, and Pointer (WIMP) interface, much like the one you probably already know and love. It's not a one-to-one match with XP or Windows 7, but most Windows users will find Cinnamon a comfortable fit. Linux users who grew up with the GNOME 2.x style interface will also love Cinnamon since it's based on that classic Linux desktop interface.

3. Zorin OS

• Windows-like user interface
• Intuitive user experience
• Easy to use
• Huge collection of software applications available through the software center Essential tools pre-installed
• Ultimate edition available with a lot of pre-installed goodies and Lite edition for older computers

So you really, truly dislike the thought of learning even a small amount of GNOME. In such situation, try Zorin OS. It is built on Ubuntu, much as Mint. You may use the Zorin Appearance software to give the desktop a Windows look and feel. Alternatively, it may offer you the appearance and feel of a Chromebook or Mac. Zorin is extremely adaptable. Zorin exists solely to assist you in transitioning from Windows or macOS to Linux. It also includes material that is particularly designed to assist you transition from Windows to Linux. Zorin is available in three versions: Core and Lite, which are free, and Pro, which can replicate the Chromebook, macOS, or Windows appearance and

4. MX Linux

• Lightweight Linux distribution
• Easy to use and simple
• Most downloaded distro according to distrowatch

Today, it's a good, solid lightweight desktop that uses Xfce as its interface. It works well, and it's very popular. What I like most about it is that it's beginner-friendly, easy to pick up, and you can run it on even ancient Pentium II gear. In short, it's ideal if you want to get your feet wet with Linux on a PC that would otherwise be collecting dust in your closet.
But you don't have to take my word for it. On Distrowatch, the one site that tracks all the Linux desktops, in recent years, MX Linux is almost always at the top of the list. They must be doing something right.

5. POP! os

• Improved user experience when compared to Ubuntu
• Good choice for gammers there
• Extra out-of-the-box features like Auto-window tiling to help with fast multitasking

If you don't need a lightweight Linux distribution, Pop OS is arguably the best Ubuntu-based option.
When compared to the Ubuntu GNOME version, it offers a more refined and responsive user experience. Pop OS also has some unique features such as automated window tiling, window stacking, and a few more goodies. You receive Cosmic, a desktop environment based on GNOME, with various modifications and built-in extensions to improve the user experience.
Unlike some other alternatives, it does not support various desktop environments by default. If you despise GNOME, you may need to explore with different desktop environments. You may find the new features of Pop OS 22.04 beneficial for learning more about it.
