There may be some practical differences to consider:
Freshness: Nuts with shells may stay fresher longer than pre-shelled nuts because the shells protect the nut from light, air, and moisture. Pre-shelled nuts are more vulnerable to rancidity and may have a shorter shelf life.
Convenience: Pre-shelled nuts are generally more convenient to eat than nuts with shells, especially if you are in a hurry or don't have a nutcracker. However, some people find the process of shelling nuts to be therapeutic and enjoyable.
Cost: Pre-shelled nuts are generally more expensive than nuts with shells because they have been processed and are more convenient to eat. However, the difference in cost may be minimal, depending on the type of nut and where you buy it.
