Is more amp power always better...?

You want good quality.

This would give you class A power and enough of it. I'd say this would be your amp.

Just like a hot rod , more is better.

Being a bit underpowered at "normal" listening levels will result in some degree of dynamic compression. The result will not sound "wrong" or objectionable, just not as impactful, or with as much contrast between quiet sounds and loud ones. Severe clipping due to insufficient power at high listening levels is another story altogether. Not what we’re referring to here.

On the other hand, the "wrong" high powered amp will sound wrong to you, which would be objectionable.

So, pick an amp that sounds good to you.

Please don't associate watts with sound quality.    In a 500 wpc amp, if the first watt is crappy, the remaining 499 watts will be crappy.  I have a 40 watt tube integrated amp driving speakers rated at 92 sensitivity.  I can blow the roof off with volume (not important to me).  Most important:  The sound quality takes me places my car can't.

The answer to the title of your post is:  No!

I know this is frustrating but I've found that the manufacture's stated WPC has very little to do with true, usable power output.  One really has to do a deeper dive and either listen in person or get information from a trusted source like an informed friend or dealer.
