Is 100 watts good for an amp?

Excuse me, I'm curious about the suitability of an amplifier with a 100-watt rating. Could you possibly elaborate on whether 100 watts is considered a good or sufficient power output for an amplifier, taking into account various factors such as the type of audio equipment it's paired with, the size of the venue or space where it's being used, and perhaps even the personal preferences of the end-user? I'm looking to gain a better understanding of whether 100 watts would be an ideal choice or if there are any potential limitations or considerations I should be aware of.
