Rather than a planisphere, I’d go with S&T’s Pocket Sky Atlas.
They perform totally different, almost non-overlapping jobs.
A planisphere shows the constellations and possibly a smattering of the brightest deep-sky objects in very little detail, but is ideal for telling you exactly which parts of the sky will be visible at any season and time of night.
A star atlas shows the sky in considerable detail, displaying far more stars than any planisphere as well as hundreds or thousands of deep-sky objects. But it doesn't help tell you what's visible when, nor help in orienting the sky to the horizon.
I agree that the Pocket Sky Atlas is the overall best choice of star atlas for most beginners -- and many other people as well! But I could easily name and defend ten other plausible choices. Don't get me started!
Sky Safari Plus can do more than all existing print star atlases combined, as well as all planispheres and astrolabes combined. But it's not nearly as pretty -- especially compared to an astrolabe.
In case you're curious, an astrolabe is neither more nor less than a planisphere, but realized in metal rather than plastic and cardboard.
