Wattage doesn’t equal audio quality.
All things being equal/ assuming you have 2 exact amplifiers (other than their wattage output), the one that puts out more power, say twice as much is going to give you better audio quality. It will not strain as much and will have better headroom and dynamics for a specific output level. Picture a 4-cylinder car versus an 8-cylinder car going up a steep hill.
Keep in mind that most amplifiers are performing at their best sound quality around 15-30 watts of output, regardless of their maximum/ rated wattage output. It’s when you go past those 15-30 watts that thing begin to change. This can be seen on a graph from manufacturers that publish that information or individuals that perform tests and publish them online.
I would concentrate more on the "sound characteristics/ signature" of an amplifier more than on wattage, but if you can have and afford both the sound signature and the wattage, why not?
For what it’s worth, I very rarely exceed more than a few watts (literally) on any of my systems, but have several hundred and even thousands of watts on a couple of them waiting to be used when and if I get that urge to crank up some music, although my desire to do that has diminished with age.
