Simple. The two 10 amp outlets are basically a mechanical switch. They are able to handle a higher load but make a clicking noise when they activate.
The rest of the outlets are solid state (no moving parts) silent operation but have a lower current capacity.
If you are controlling a low power item that cycles often use outlets 1-3, 5-7. If it's something higher power that doesn't cycle often outlets 4 or 8 are preferred.

I agree with most of what you said, outlets 4 and 8 won't handle as many on/offs as the solid states and will eventually start arcing but it also depends on what you're plugging in. TRIAC outlets sometimes fail with very low voltage devices and will fail in the on position. If your running dosing pumps or any other low draw device I would run it on outlets 4 and 8. This is what Neptune says:
One problem with TRIAC controlled outlets however is that they sometimes cannot detect very low power factor devices and as a result may not switch off correctly. They fail in an ‘on’ state. This only happens with very low power devices, < 4-5 watts. So, if you have any device like that, you might consider putting it on outlets 4 or 8. Dosing pumps and very small power heads are good examples of problematic devices with TRIAC outlets.
You all have been so helpful, and I really do appreciate your inputs. Just so I can keep up with all of the helpful advice (I have three major threads going at the same time),
