I see where you’re going however I would present an alternate view on security.
A key is physical and fixed. (You can rekey but it’s painful). You can lose it, it can be stolen or copied. If anyone has your key or a copy of it they can unlock your door.
Key codes are virtual, ie you don’t carry anything. Plus you can change it instantly. So if there are prying eyes it’s a breeze to fix.
The other type is presence. Now that’s half way between a key code and a key. It physical like a key. Means it’s can be stolen or lost (not copied). If someone has access to your presence sensor they can now not only unlock your door it also disarm your security system and actually compromise your security more than just having a key.
While a key code still needs to be typed it is inherently more secure than a presence sensor.
Having said that yes a presence sensor is “easier” to use since you don’t have to use your hands (well you still need to unlatch and open your door).
So it’s a trade off between security and convenience 
As for looks the Yale YRD locks look just a sleek. In fact some models like Connexis support both keypad and RFID tags.
