Controversial but Apple. I like that they keep things really simple and are really clear and focused about what they're trying to accomplish. I've been trying to go minimalist and often you need a rich and powerful role model to justify that cutting features will make more money.
MacBooks are probably not the best example. But the screens are clear and the processor is beautiful. Airpod and the old iPods were my favorite example. I also loved that Android rewrote their design when they saw the iPhone.
