While brutal, I believe the assessment below does have some merit :^)
As usual, the real choice between these two tools should be based on
what you use them for and how you use them. We've found that both tools
are equally capable and accurate (given good models and a reasonable
amount of "hands on" time).
If you like to batch up large numbers of simulations (to play around
with various termination options, for example), you'll want a tool with
the capabilities of PCB SI. While it will take you a LOOOONG time to get
the models loaded and the sims set up, you will get a bunch of data
back. It can be set to flag particular measurement limits, so you can
kick it off, and come back later to see if any of the batched sims
failed. Great for big, wide busses, where you essentially run the same
sim many times. If you use this tool every day, you might even get good
at it. Just don't expect to sit down at it once every 6 months or so and
remain proficient.
If, on the other hand, you like to get quickly to a given sim, and don't
mind driving the tool more interactively, Hyperlynx is great. It's easy
to set up, actually accepts native IBIS models without translation pain,
and is relatively intuitive to use.

I recently received a comment about just this from an acquaintance:

"Short answer: anyone trying to make full use of Cadence pcb si tools
for
interconnect sim and who, nevertheless, recommends it could make good
use of
counseling of some kind... or the receivers of that info could make good
use
of a polygraph test on the one recommending. All this based on 1st
hand
experience over time."
