I'll be explaining some things about Linux as seemingly the guy asking the questions should have some clarifications about this naturally! I'll go one by one though:

Regarding DEs/WMs and their CPU/RAM usage: When you pick a Linux distribution, you expect it to have some sort of DE already installed by default or networking tools that let you download, configure and sometimes even compile the DE or WM of your own choosing. The reason why many people go and ask "When I tried xfce after GNOME3, it was a revelation!" can be due to a number of reasons.

If they feel is lighter, well, they are right. The difference between DEs comes down to the taste of one's person in particular, but the reason why some DEs feel "heavier" than others is due to the resources they need in order for them to function properly. In the case of Xfce, the reason why it feels lighter is because it does not needs GPU rendering, Hardware accelerated graphics or 3D rendering like GNOME does and so xfce can work completely fine even with software rendering alone. Among xfce in the DE crowd you get the even lighter LXDE and LXQt (the latter being actively developed and the former still having the occasional update) and the teensy-bit-heavier than xfce MATE DE.

However, all of those do not require hardware acceleration and can work with software rendering, which is why when someone uses them on say, older computers, they won't feel the weight of something like GNOME3 does due to those aforementioned causes. The distro implementation of a DE may help you in getting it running faster than ever if that distro aims for desktop usage (like say, Manjaro with its GNOME3 variant, or Solus) but they won't reduce the functionality or the weight the DE itself has, only give you a little helping boost here and there when needed (Which is usually not significant because again, it depends on how well the DE itself is handled by its upstream developers)

WMs are not DEs. When you use a DE like Xfce or Mate, you expect it to come with a File Manager, an audio player integrated, some other desktop tools integrated, etc. WMs do not come with any of those, they can focus or help you giving some graphical interfaces but at their core they are much simpler to maintain and develop than DEs because they do not rely on giving you the full kitchen sink. WMs are extremely customizable and you can "rice" them however you like because they are meant for those who like to tinker, read scripts or modify them to their core. Some WMs however (IceWM or Fluxbox) do help the end-user a little bit with their windows, effects and graphical management but overall won't hold your hand with additional tools or anything else, you still have to do your homework when maintaining those.

Regarding Security: Security is a process, the reason why many people feel Linux is secure is because indeed it is! however, the user must still be aware of how to operate their computers well and make the administrations tasks needed to perform them. Use root when doing tasks that a regular user can't do and then go back, however, I shall tell people not to be afraid of root, only that they should understand the consequences of what that much power entails.

Many Linux distributions also come with a package manager, repositories, options to add more repositories and if the user is willing they can also compile the source of a program into their machine in case the software they desire is not available in their repos. This greatly lessens the risk of any user who installs a Linux distribution, add to that: Linux kernel and updates rolling in for all distributions constantly + Patches for every imaginable kernel that it would be impossible to affect something + Monolithic design that allows the OS to be separated from its UI elements (unlike Windows) + Separation of the root and regular user clearly + Designed to handle multiuser setups from the get-go.

All of those above make it extremely unlikely to get infected on a Linux machine, you really need to go out of your way to be infected or have even one virus on Linux (Most of the viruses are written for the servers anyway, which is where Linux absolutely dominates, but desktop or embedded users need not to worry). In opposition to Windows which is...a joke regarding security to put it lightly.

Well, I hope I clarified something with this much info!
