As with many things, this depends on your personal preference and preferred taste profile. On one hand, whole beans are fresher, more flavored coffee, and produce a high-quality taste in a beautifully crafted coffee.  Ground beans are obviously coffee beans that have been grounded, and so they may have lost some aroma and flavor in the process. However, ground coffee is far more convenient and can be used instantly.  You may prefer pre-ground coffee as it will save you some time, and if you are anything like us in the morning, then time is key. You may not want to stand around and start grinding up coffee for your French press as soon as you wake up, just so you can have a nice brew, so pre-ground coffee is the way to go.  On the other hand, coffee beans are packed full of divine, distinguished, and beautiful flavor. You will have to grind the beans before you even think about the brewing method, and will have to grind them evenly for a good cup of coffee. Without grinding, you will not be able to extract a strong flavor from them, and will not get that glorious coffee taste that you want. It kind of all depends on whether you are comfortable with sacrificing a little flavor to save yourself some time, or prefer to be a coffee connoisseur in the morning.
