The verdict
One difference, none of them an advantage
The largest is open-circuit voltage: 1.43 V apart. 17 of 18 comparable parameters are identical, with 1 more left out because at least one datasheet does not publish it.

What it means on a roof
Thirty years of production
Declared first-year losses, with 0.40% a year afterwards assumed for both panels, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.350 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.
