Shimano 105 DI2 vs Mechanical 105 + Power meter + Bike computer

Hello Reddit,

Looking at the Merida Scultura Endurance series and need some help deciding on getting the nicer bike or the lower spec with bike computer and a power meter. The bikes are identical other then the DI2 groupset difference.

Scultura Endurance 4000 (2600$) + Edge 540 (370$) + 4iiii Precision 3+ (480$) = 3450$

Scultura Endurance 6000 is 3400$

So what's more worth it? DI2 or Computer + Power meter?
