Pegasus has a 5% failure rate. Taurus has a 33% failure rate. Taurus has three failures in its last four flights. Not impressive. SpaceX had a perfect launch record on the Falcon 9. Not bad for a 12 year old company. And regarding Boeing being 100 years old, I'll drive a Tesla and not a Model T, thank you.
Please read my post carefully. Right now yes, SpaceX is more qualified. That was not the case in 2008 when CRS contract for SpaceX and Orbital was awarded, both SpaceX track record and success rate were far inferior.
