New Workstation ECC vs non ECC / Xeon E2286M vs i9-9980HK

Hi 
I´m about to order a new laptop and I have chosen the Dell Precision 7540. 
Im a little bit confused on what to choose, since I have read that the Xeon with ECC performs a 1-3% slower than the i9. But when reading some benchmark tests I can see that the Xeon combo almost always beats the i9. I will be using the worksation for After Effects, Premiere Pro, Photohshop, Indesign and Illustrator. 
Theese are the configs im going to choose from:
