Popular Gamemodes/Add Ons?

I used to play garrys mod all the time. i really liked the space build game modes and all the crazy weapon add ons people made. i dont mean sweps i mean the weapons you could attach to vehicles and fire using buttons, etc. I just recently got a working computer that can handle garrys mod but i have no clue where to even start anymore haha, i remember the pheonix mods and all that but i was just wondering what you guys are all playing now. So any suggestions would be appreciated
