Head to head
One is a computer on your wrist. The other is a sensor with a membership. Here is what each does well, and how to get recovery scores from either.
Short version
If you want notifications, apps, GPS and a screen, the Apple Watch is the obvious pick and its sleep and heart data is excellent. If you want a screenless band with days of battery and do not mind a yearly membership, WHOOP is the specialist. The recovery score is not exclusive to WHOOP: with an app like Sixteen, an Apple Watch gives you a daily recovery, sleep and strain score too, and Sixteen can read a WHOOP strap directly if you already have one.

Both measure heart rate, HRV and sleep well enough for daily recovery. Apple Watch adds ECG, blood oxygen on supported models, wrist temperature, GPS and fall detection. WHOOP adds skin temperature and blood oxygen on its strap and continuous beat to beat data over Bluetooth.
Apple Health stores sleep stages, overnight HRV, resting heart rate and respiratory rate; recent watchOS adds a sleep score. Apple does not compute a recovery or readiness score. WHOOP's whole app is built around one. Third party apps close the gap on the watch.
Apple Watch: roughly a day to two, charged daily, with a screen. WHOOP: four to five days, charged on the wrist, no screen. This is the real lifestyle difference.
Apple Watch: buy once, no membership, from a few hundred dollars. WHOOP: $199 to $359 a year with the strap included and no way to use it without paying.
