Mixing in stereo is a great way to separate the elements of a mix and make them easier to hear. However, when you convert the mix to mono, these elements start to darken again. This is why some producers prefer to mix in mono for most of the process. Mono not only provides clarity when listening, but also helps detect errors in the mix.
When you mix in stereo, it can be difficult to spot errors due to the secondary information coming from the sides and center. On the other hand, if your mix sounds great in mono, it will sound even better when you switch it to stereo. This is because you will be able to perceive different volume balances coming out of each speaker. Additionally, mixing in mono can help you avoid phase cancellation issues that can make some sounds appear lower than they actually are when mixed in mono.
To ensure your mix sounds great in both mono and stereo, it is best to start by mixing in mono first. This way, you can easily spot any errors and make sure your frequencies aren't colliding. Logic Pro has a Direction Mixer add-on or its Gain add-on, which includes a mono switch that can help you with this process.
