With PEA added, what fuel has better cleaning?
What fuel cleans better, ethanol free or E10?

Dry E10 helps remove water from the tank.
In terms of cleaning it’s complicated, ethanol tends to draw in baddies as much as it cleans being a wash.
Ethanol tends to foul oil faster if you have a car that dilutes oil

Probably the E10, but the variation from station to station and brand to brand is enough you'd never be able to prove it.
Ethanol is a polar solvent (electro-negative) but is capable of dissolving both polar and non-polar compounds as the core ethyl group (C2H5) is non-polar and thus attracts non-polar molecules. This matters when it comes to valve and chamber deposits, largely contributed by oil vapor, which are organic polar compounds. Gasoline is a mixture of aromatics, alkenes, alkanes, and cycloalkanes. The aromatics like toluene and xylene, containing a benzene ring, are non-polar solvents. The alkanes, like 224TMP, are also non-polar solvents. It's much the same for alkenes and cycloalkanes. You won't get much cleaning of polar compounds with ethanol-free gasoline. You will with E10 as the ethanol introduces a polar solvent.
I am looking to clean combustion chamber deposits.
I’ve always used top tier 87. Bottle of Redline SL1 before each oil change.
