Is a 30 watt amplifier good?

I'm curious, is a 30 watt amplifier really considered good? I've heard varying opinions on this matter, some saying it's plenty powerful for most needs, while others argue that it's not enough to deliver the kind of sound quality they're looking for. So, what's your take on this? Can a 30 watt amplifier truly be considered a good choice, or are there better options out there?
