That depends on how long it is turned fully off for.
One thing for sure is that turning it on after it has been turned fully off requires it to run at maximum power for half a minute or so as it boots up the OS, and as a result, the indicated battery level after doing so will likely be somewhat lower than it was before it was turned off (but it may well climb after it is turned on if you don't run anything intensive on it).
Putting it into the normal standby mode allows near instant startup with no additional battery drain, but it will be using a small amount of power to maintain that mode.
Unless you are not going to use the device for over a full day, then I reckon the best policy is just to put it into standby.
