"thru-axles tie the fork or frame together in a much stronger, stiffer way"
I don't believe reviews that are based on rider feel. If he had some kind of device measuring flex in the fork legs I'd pay more attention to it. Maybe it doesn't make any diff. in rigid forks but without data it's not swaying me either way.
There's likely a reason all the MTBs went to thru-axle. If it's stiffer with suspension forks it 'could' be stiffer with rigid forks. Since most newer road disc bikes are coming with thru axles it seems silly to go backwards to QR, regardless of the actual flex values.
