Like everything in engineering, it depends on the specific application.
The maximum width dimension is the same for both parts, 0.3mm, so it’s only the nominal and minimum dimensions that have a difference, and the difference is only 0.02mm. I’ve never designed a PCB that would have a problem in production if I design for the wider variation and the parts were produced with less variation components.
I’ve never even worked with a PCB manufacturer that can reliably produce boards with an accuracy of better than 1mil / (0.001" / 0.0254mm / one third the diameter of a human hair), the ones I’ve used have allowed variation of +/-2mil / 0.0508mm.
However I’ve never designed a PCB for a product like an iPhone so I’m unsure if incredibly tight accuracy is required with those types of PCB assembly (high speed robots). So I recommend you consult with the manufacturing engineers responsible for the specific assembly process being used.
