While I cannot comment on specific pricing, I can try and fill in the rest of the blanks.
In regards to hardware device, there will be the initial cost of the hardware and the annual cost to support next day or same day for RMA support. In regards to software, the two options you are referring to is perpetual license (individually) compared to the essential suite.
In the perpetual license (individually), this will only be the user license and will need to add the additional cost of gold or platinum software support.
In essential suite, the suite will include the gold or platinum software support, user licenses and Pulse One (cloud) solution to help manage the device (useful if you have more than one devices to manage).
Pulse Secure have try to simply the software packages to essential, advanced and enterprise suites. I've found the following document helpful to others trying to determine differences in each suite. Though, we do understand that suite may not make sense for everyone and still allow to individually purchase user license without having to purchase a suite.
Hope you've found this information helpful.
