Is 5 watts amplifier good?

Hello there, I'm curious about the performance of a 5 watts amplifier. Now, I understand that wattage is a measure of an amplifier's power output, but does a 5 watts amplifier really deliver good sound quality? Is it suitable for a variety of applications, such as home stereo systems, guitar amps, or even car audio systems? Additionally, what are the pros and cons of choosing a 5 watts amplifier over higher wattage options? I'd appreciate any insights you could offer on this matter.
