I've been using Pop Os for a few months, and quite like it as a step to see how things work in Linux world.
I've also looked for a lighter distro for my 2011 laptop to replace Win7. Yes, there are plenty of them, but still, they tend to include way too much stuff, that I'll never use.
Make a custom Linux iso then? Meh, I tried that using Cubic, but don't know how much can be removed until something breaks. Dependencies I guess.
How about even lighter distro, where it's possible to install only needed apps?
Lately I've been testing server versions of Ubuntu and Debian in VM. In other words, 'headless' ones that doesn't have elements like desktop (or actually anything that uses GUI) as a default.
Anyway, there are tech guys on Youtube, who show the steps how to make a minimal Linux installation with desktop using server distro.
What comes to desktop environments, I've tried Xfce, Lxqt, and Mate.
At this point, Mate seems to be the closest to what I'm looking for, for its lightness and customization options. It even allows using window borders in its themes without the need to mess with css files. An example of classic Window-ish GUI:

Ubuntu Mate uses Snap (which is a service running at background) to install and handle apps like Firefox. Like with Windows, I don't like such unnecessary services hanging around, and Snapd is one of them. Obviously, disabling that breaks some things.
Debian Mate doesn't seem to use Snap out of the box, so I'll stick to it for now.
So, this is about finding out how usable, reliable and perhaps snappy such a minimal system can be, when compared to 'full' distros like Mint and Pop Os.
In the end, bit of a rant:
Pop Os that I use on my pc, is quite resource heavy. When having something like Virtualbox and two web browsers running, it occasionally freezes the host system, VM or both.
I have 8Gb of ram on my pc, and don't remember having that kind of issues with Win7. From what I've read, it's about different memory management/allocation. There probably isn't much that can be done about it, except adding more RAM.
