Have to be careful when judging these graphs visually (note to self as well)! Mine was wider than
@XMechanik's, but we match when you ensure all else does. From a relative perspective his animation appears to be a fair comparison.
Just to illustrate...

These are screenshots of the same crossover, scaling and graphic dimensions, but without the legend, the lower one is more stretched horizontally and so appears flatter.
Yes, the original crossover is a bit better but as you found, it comes at a cost. Often a designer will optimize a crossover for more common component values to help lower cost. If you remove that constraint, you can tweak the crossover for better performance at minimal added cost.
