SpaceX created the first successful Full Flow Stage Combustion Cycle Engine, so they’re also innovative in the propulsion department.

SpaceX has only had 2 mission failures out of 274 total missions. Since 2017 SpaceX has had a 100% success rate which is a vast majority of its total missions. The recent explosions have been test rockets and expected to blow up, it’s how they learn and innovate so quickly. NASA takes billions of dollars and 10+ years to successfully launch a rocket on the first attempt. It’s just 2 different approaches to design and innovation.
