I feel good striking is often about having good fundamental habits.
Train both but more so on pads do the 'watch'. This ensures your elbow goes up at a good angle, this can feel weird to those who learnt 'stirring the pot' first.
If one trains only the 'pot' then an ugly habit of the elbow dropping can start to become your norm. Under pressure and whilst being hit we tend to lose exact position and technique a bit anyway and the elbow dropping is one of the first ugly habits which manifest.
Training the 'watch' reduces this ugly habit. I still do the odd 'stirring the pot wallop' and it feels awesome, but, for experience I learnt that for me, a reliance of the 'pot' seemed to make this ugly elbow habit happen more and poorer technique became more obvious.
The above refers to striking to the head mostly. For the body I find that with boxing gloves the 'pot' gives a better angel for both speed and power, especially if you have a bit of distance between you and your target.
With MMA gloves and in a sort of standing clinch I find positions where the 'watch' is better though.
When you meet the unbelievers in the battlefield strike off their heads and, when you have laid them low, bind your captives firmly. Quran 47:4
