What separates The Ranch from Fuller House is the level of professionalism and craft on display. Kutcher and Masterson, who play brothers named Colt and Rooster, may not be the most versatile actors, but they know how to sell the hell out of jokes about driving trucks, drinking whiskey, and having sex with sheep. That's one thing The Ranch has on all the other sitcoms out there: no other comedy makes as many jokes about having sex with animals. Not even BoJack Horseman.
More important, Kutcher and Masterson know how to sit in the little pockets of drama the show creates and even end the occasional scene without a punch line, giving the show a melancholy touch. Similarly, legendary character actor Sam Elliott, who plays the boys' cranky father Beau, brings a weary gravitas to all his scenes. He makes out-of-touch-old-man jokes like, "What the fuck is Adele?" and "What the fuck is Tinder?" sing. The character's anger and resentment feel lived-in. His pathos feels earned.
