Question Car Ferry Routes to the Isle of Mull

I'm planning a trip to the Isle of Mull and trying to figure out the best way to get there with my car. I know there's a ferry, but I'm not sure if there's more than one route available. Does anyone have experience with the different car ferry options to Mull? I'd appreciate any advice on which route might be the most scenic or convenient. Also, any tips on booking in advance or what to expect during the crossing would be great!
