I often use time as a form of pressure/constraint on PC action- so there is often conflict of player choice- does the opportunity cost/benefit of taking ten outweigh the cost/benefit of rushing the action?
Seen in a vacuum, taking 10 or 20 is always going to be superior to simply rolling. But I haven't played in a vacuum since Star Wars d20
Unlike Take 20, Take 10 has no opportunity cost. The time required is identical.
If a 10+ is known to succeed and the circumstances are calm enough to allow it, taking a 10 is superior. Rolling is superior when (a) Take 10 isn't an allowed option, (b) the required target on the d20 is 11+, or (c) the required number is unknown to the player and the player wishes to maximise the rolled value.
