I own 7DII and 5DIII and for sure on my 7DII in AI servo mode AF is a bit less precise than on 5DIII. Not a big difference but after 10000 shots (macro shots are included as well) I can confirm that. However regarding APS sensor size the needed shutter speed must be higher and must be considered all effects (air thermal differences, IS setup etc). Hope you will resolve the issues.
Cheers,
