That's quite the generalization!
In the past.......Asian brands have used simple Analog 2-wire A/C Sine Wave producing CKP & CMP sensors just about exclusively, This type of sensor has NO electronics to fail & are for the most part VERY reliable.
In the case of a Northstar.......The CKP is a Digital 3-wire DC Square Wave producing Sensor that is powered & grounded for the built-in electronics. Most all Domestic engineered GM engines use this style along with most Chrysler designs.
Ford used mostly Analog CKP sensors 'til the Ecoboost came out.
Electronics do not like heat, This alone will cause Digital sensors to fail more often than Analog sensors.
With advanced engine management needed to control Direct Injection &/or Atkinson Cycle-Valve Timing.......Digital CKP & CMP sensors have become a necessity for resolution/accuracy that Analog signal generators CANNOT achieve!
Ironically........Toyota had some issues with the implementation of this "New to them" technology that resulted in a CKP Sensor Safety Recall on some early 2GR-FKS engines.
IF this turns into a pattern failure-100,000 mile sensor like the FWD "Dual Sensor" Northstar's.......Will you or any other Toyota fanboy call these Denso sensors cheap junk? What if they randomly fail like most other Digital CKP sensors??
Why can't Toyota owners be more pragmatic when it comes to other brands......GM/Chrysler/Bosch were Innovators to use this technology 30+ years ago!
