Which amplifier is powerful?

Excuse me, I'm a bit confused about the amplifiers you're mentioning. Could you please clarify which amplifiers you're referring to? Are we talking about audio amplifiers for speakers, or perhaps some other type of amplifier? If it's audio amplifiers, are we comparing them based on wattage, frequency response, or some other metric? Without more context, it's difficult for me to give a definitive answer to the question "Which amplifier is powerful?" Could you please elaborate on your query?
