Trip grading metric

Inspired by Only Solitaire, I wanted to try grading the various Future birding trip ideas that I have cooking, to help prioritize among them. Also helpful to look retrospectively at Past major birding trips for which I enjoyed the most.

These are the categories that I'm considering, and the factors that go into them. For simplicity's sake, start with each getting equal weighting.

Birding quality

Among places I have visited so far, I would place Western Mexico towards the top of this scale, with exciting new birds coming in thick and fast.

Logistical ease

I would probably rate the United States highly on this front, largely because it's what i'm most accustomed to, but also obviously because of its high development.

Culture

Bang-for-the-buck

Examples

These should get broken out to their respective pages. Is there a need to collect them here? Maybe superlatives for each category?
