attrset ? "key" and attrset.key or fallback have nearly equal complexity costs
if attrset ? "key" then attrset.key else fallback is slightly more expensive,
due to being 3 AST nodes (an ExprIf with an ExprOpHasAttr as the condition and then an ExprSelect to extract the "key")
attrset.key or fallback is slightly cheaper, since it is a single AST node (just ExprSelect)
