Switching to powder has done a lot for us in getting dishes cleaner, and we can dial in the amount of powder needed for the particular soil level of a load.
The fact that it's cheaper per load, and the box fits more neatly under the sink are added benefits.
And if your hands are slightly damp, the cardboard box for the powder doesn't stick to your fingers, where a dissolvable membrane would start dissolving on you.
The pouches are still pointless.
We switched and it almost completely solved our "dishes not getting cleaned properly" problem.
