I do not have either one of the drives you're considering, but I did upgrade my older laptop to an SSHD a few months ago. I really see very little difference, if any, between it and a straight HDD.
Of course, that's probably largely because of my usage patterns. If you have several files you access constantly that will fit into the SS part of the SSHD your access to same will be very much faster. If you're like me, randomly flitting about doing all sorts of stuff at random, you're still mostly having stuff fetched from the HDD and, even if placed in the SS part, quickly rewritten out to the HDD when you're finished.
I had not given that any thought when I bought the drive, and have no regrets about doing so, but usage pattern really makes a difference in how much improvement you will, or won't, see with an SSHD.
