The last few weeks, I've tracked all my gear drops, and my conclusion is:
- I'm tired of doing it.
- My observations seem to confirm the drop rate for one item is the same regardless of the node it's farmed on, in particular are not better on hard nodes.
- Seem compatible with green = 50%, blue = 33%, purple = 25%, newer gear (purple and gold) = 20%

So here is the result. The table should be self-explanatory, but otherwise, here's a little legend:
Row 1-2: Node. Colors are just noting the ones I find more useful
Row 3: Energy
Row 4: Number of attempts
Row 5: Character shard drop
Row 6-9: Gear drop, in the order they are listed in the game (colors might indicate what gear)
Row 10: My personal score for that node, based on the gear I need
Row 11-33: Drop rate per item and per node
