-`fast-safe-stringify` is 2x faster for small objects, 
-and 6x faster for large objects than `json-stringify-safe`.
+## Protip
 
-`fast-safe-stringify` is 4x faster for small objects, 
-and 9x faster for large objects than `util.inspect`.
+Whether you're using `fast-safe-stringify` or `json-stringify-safe`
+if you're use case consists of deeply nested objects without circular
+references the following pattern will give you best results:
 
+```js
+var fastSafeStringify = require('fast-safe-stringify')
+function tryStringify (obj) {
+  try { return JSON.stringify(obj) } catch (_) {}
+}
+var str = tryStringify(deep) || fastSafeStringify(deep)
+```
 
+If you're likely do be handling mostly shallow or one level nested objects,
+this same pattern will degrade performance - it's entirely dependant on use case.
