Laser tube Wattage vs engraving quality

[Peleacios]

So, all things equal, considering you have nice/clean lens and mirrors, the tube itself is good, power supply, etc and that the machine carriage and everything else is solid and is not adding quality loss...
How much of an improvement is engraving with let's say a 60W tube vs a 120W one?

I ask because I am on the verge of getting a new machine, and since now dual-head machines are more popular and affordable, I was considering a 60w+120w setup, rather than a single 100w setup.
That way I have a bit more power for cutting with the 120w tube, while more quality for engraving with the 60w tube...

But is that thought right?

My experience is with a RECI 90W.... which sometimes was a bit underpowered for cutting, and although I can't say the engraving quality was bad, the fact it won't reliably fire under 14% means sometimes it's a bit too much power for very fine engraving on paper.

What is your experience?
Makes sense 60w+120w dual head over a single 100w?

Cheers

Dual watt would be good for both worlds, I do know the higher wattage is not good for intricate engraving.

If you cant have a REAL laser like Synrad that makes sense.

Yes,the watts matters, you can use a 120w laser tube as a 40w laser tube when adjusting the percent, but 100w couldn't adjust like a 120w.
