That’s a very common dilemma, and honestly, there’s no single “perfect” method. That said, eddy current testing is often underestimated when planning inspection systems. Its flexibility is actually one of its strongest points. It’s fast, doesn’t require couplants like ultrasonic testing, and works especially well for detecting surface cracks, corrosion, and material inconsistencies.
In our facility, we introduced eddy current testing early because it allowed quick screening of parts before more time-consuming methods were applied. It saved us a lot of time and reduced false positives later in the process. This overview helped us internally when making the decision, as it clearly explains capabilities and limitations:

If your components are conductive and surface integrity matters, it’s definitely worth early adoption.
