Which Adobe Reader version would you recommend for enterprise?

We currently have Adobe Reader XI deployed and should migrate to newer version soon. However, as far as I know there are three options available:

• 2015 (Classic Track)
• 2017 (Classic Track)
• 2017 (Continuous Track)

We have decided to use Continuous Track for Acrobat. Which option would be the best for us? Could the be any compatibility issues with using Classic Track for Reader while using Continuous Track for Acrobat?

Thank you very much in advance.
