Personal opinion really
In the last couple of years I’ve gone over to lock lids whilst the majority seem to have gone away from them
For pods on a functional basis, the standard fat boy pod is spot on.
If you watch a tournament field then that’s what you will see (though to a degree as they dump them to be picked up later then that can be accounted for with the risk of loss, plus the expense to a team of having a pit crew keeping enough pods ready filled for 5 people to get back on field quickly)
Lock lids lock, but there are people who can still spill their paint from a lock lid behind their back
They can hold more per realise due to the dimples, but are you really going to plan on going right down on paint? you will see players pouring half a pod in and having half left - so they either spill it or are left holding a half full pod
They may not fit all pod belts, or are tight and difficult to pull out - therefore at more risk of popping open and wasting paint
