Top 10 addons

10 Place. media player
This addon is very simple: you can watch your favorite youtubers, watch streams, guides, listen to music, etc. together with friends, seeing the same thing on the same screen, this addon has small screen, medium screen, big screen. Just place the screen, press C while aiming at the screen, add a video, and you can watch Youtube, Twitch, etc. right in Garry's Mod. It's simple!
9 Place. bail out
Everything is simple and clear: you assign a button to eject and lunge, and when you are in a seat or any other object where you can sit down, press one of the buttons, you eject, or fall out of the seat like a Ragdoll model, and then get up. Enough epic addon with which you can indulge.
8 Place. WAC Aircraft
This mod adds aerial vehicles: planes and helicopters that can fly.
There is nothing to explain either, except that in this addon planes and helicopters can be damaged from falls, from explosions and from bullets. If the helicopter's rear propeller is torn off, then the helicopter will not be able to turn, and will simply fly up, and if the main propeller is torn off, the helicopter will fall, and in many cases, crash. And if the propeller is damaged on the aircraft, then it will start to fall, but it can hover, if the aircraft has engines (left and right) for the propeller and they are damaged, then it will start to mow in one of these directions. I also forgot to mention that some planes and helicopters have machine guns and rockets, and some planes have bombs. Here are images of some planes and helicopters:

7 Place. M9K
There is not even much to say about this addon, these are just awesome weapons with high graphics, good sounds and a lot of weapons. I'll just show the list of weapons:
Heavy weapons

Sniper rifles

Shotguns

Pistols

Machine guns, submachine guns

assault rifles

6 Place. PAC3
The addon adds changes to your character's body, namely: bones, adding items, animations, trails, texts, scripts, commands, and much more! With the help of this addon, you can easily make yourself like this: Or here's what you can do with average knowledge of the addon: Also, this mod allows you to turn the Ragdoll model into your skin, and also change and distort it further as you want! There is nothing more to say about this addon, everything is clear in it.

5th place. Scars
This addon adds many, many, many cars to RIDE! There are about 100 of them in this addon, and for each car there are about 10 styles, you can also paint them, lower them, change wheels, change styles, arrange races (there are special tools for arranging races), install hydraulics, put bots on cars ( they can follow the player, be criminals and be derby bots), the addon has some special tank cars Abramc and DeLorean from the movie "Back to the Future", which also "moves in time", i.e. when moving, press the letter B and it will start to accelerate, and then it will fall into "another time", and will not be visible to others, only you can see it, and fly around the world, then press B again, and you will exit the mode "another time" By the way, the famous DeLorean himself:
Here he flies simply, without time travel.
By the way, I left in the links to the addition to SCars, where motorcycles are added.
But in this addon, not only vehicles are added, in a special menu when you click on C-> SCars editor you can create your own car, but this is a mode for advanced ones.
4 Place. Drones 1/2
Above are the regular drones from this mod. But there are even more drones in this mod: racer drones, medical drones (who also heal people), military drones, kamikaze drones, cargo drones (Which carry objects using a built-in laser), etc. But how to deal with these drones? Naturally, kill with a weapon or HACK ?! Yes, you can hack using a special computer, where you can hack a drone using commands. You write a command to this computer and the hacking process goes on, it lasts about 3 minutes, it all depends on the level of the drone, there are 3 of them in this addon, they are designated as Mark I, Mark II, Mark III. But basically this mod is intended for observation (nano-drones) and for war, well, or for the most perverts, you can represent drones as Pokemon, and fight between friends on these (Pokemon)
3rd place. J.I. Defense Solutions
Actually, I wanted this addon to be in 1st place, but in the opinion of the majority, WireMod is better. What does this mod do? Nothing It adds security to your base, food, water, mines, armor, a radio (using which you can use the command to communicate with another station where this radio is located. And with the help of this radio you can order all of the above items from the dispatcher) Well, so there are many, many more, including monitoring and controlling turrets from a laptop that this mod adds, or for example:
Sleeping bags, no, you cant sleep in them, but you can set a spawn point!
Oh, and yes, dont say that the turrets (there are about 8 of them) can simply be placed and they will stand and shoot at everything and everything, no! They still need to be loaded cartridge
