IMO...
It depends on your intended usage. If you only want/need to record/edit/mix, and not much VI usage, PT10 should be a nice upgrade. Plus, you will go from LE to "PT10," which has more extras, and allows 3rd party I/O use. Since you appear to be on a Mac, then all should be well. Just check the DUC for OS and hardware issues.
Though I do not have a Mac desktop any longer, when I did, I owned Logic (ver 6-8), and ver8 was pretty cool. I preferred PT (pre-ver9) for quick recording/mixing tasks, but for composing.. Logic was a dream. There were some bugs that impacted my desired workflow, but they were (are?) obscure bugs that I found only one other even noticing. Plus, with Logic sitting at $199 for the full version now.. if you plan to stick with Mac, want to use VIs, and have some nice composing tools, my vote would be Logic. Otherwise, hit the DUC, maybe download the demo for PT10, ask questions, and then revisit your question.
PT can be such a finicky beast. The next major upgrade, supposedly, will finally include an update to 64-bit. And, a new plug-in type (already in place with PT10, but optional).
