GTA V as a whole is a great game.
For Storymode, the storyline in GTA V is one of my favorites in the Grand Theft Auto series, I beat the game on Xbox 360, Xbox One and I hope to beat it on PC (and maybe choose different paths). Rockstar nailed it on the head when it came to the characters; how the chemistry works between them and how each main character in-game is the actual face of the actor in real life.
For Online, I suggest you download FiveM or GTA Network so that you can play on other servers, than on the main Rockstar servers (for the time-being). You can you FiveM/GTA Network or you can create a private lobby from the 'Online' tab and just do heist/races in that lobby with your friends. Other than that, the base Online game is filled with hackers sadly. For a 3+ year old game, you would think they would invest money into making a anti-cheat instead of making pointless updates.
Warning; as of March 2017, you can't transfer your Online character from console to PC or PC to console. So, with that being said. You will need to start all over if you planned on merging your PS4/Xbox One character to PC. It's not possible anymore. It's funny how Rockstar can still put GTA V at the $60 price point (not worth it, get it on sale (maybe $30)), but yet they can't support a small but great feature.
