I use the Pentax magnifier and a recently acquired katz-eye focus screen. While I certainly like the magnifier, if I had to choose only one the focus screen would win hands-down.
Changing the screen was a quick and painless process, and doesn't appear to have affected my spot metering in the slightest. I've found I'm able to not only manually focus faster, but far more accurately. I can't recommend it enough if you use MF often.
I think the biggest perk of the magnifying eye-cup is comfort (it keeps my nose off the LCD), it does marginally magnify the viewfinder image, but the difference is far less noticeable (or useful to my mind) than an improved focusing screen.
