Other methods you may consider using are a disk/belt sander with a 45 degree mitre gauge, or alternatively a mitre saw. These methods are fine however you need to be a lot more careful compared to a shooting board.
Using a shooting board will mean you’re consistently taking off the same amount of material with each pass, meaning its very easy to sneak up to a precise final fit. A sander or mitre saw however will take off different amounts of material depending on how much pressure you apply, the density of the wood, the speed of the sander, or simply the alignment under the mitre saw. Of all the methods, I would highly recommend constructing the shooting board as demonstrated in this video.
