Not enough evidence
Ubiquinol is a better form of CoQ10 than ubiquinone.

Short answer
Ubiquinol, wherever a form is named. Mark Hyman recommends 100-200mg/day. It is also named for anyone on a statin, since statins block the pathway that makes CoQ10. No source on the record compares its absorption against ubiquinone; they recommend the ubiquinol form without making that claim.

Ubiquinol is the CoQ10 form named wherever a source picks one. CoQ10 comes in two forms: ubiquinol is the reduced form and ubiquinone the oxidized one. The reason matters, because it is not the absorption argument you will see on most supplement pages.
Mark Hyman, on his own show, names the ubiquinol form at 100-200mg per day for energy and longevity. His strongest point is about statins. A statin works by blocking HMG-CoA reductase in the mevalonate pathway, and that same pathway makes CoQ10.
A statin user drains their own supply and gains from putting it back. Ubiquinol is also named to protect the mitochondria, the cell's energy producers, in people on statin therapy, and for mitochondrial support more broadly.
You will read that ubiquinol absorbs better than ubiquinone, or that older adults convert one to the other less well. No source on the record says that. They name the ubiquinol form and stop there. The grounded claim is narrower: the form recommended is ubiquinol, and the clearest case for it is a statin.
CoQ10 also appears in fertility advice for egg and sperm quality, with no form named.
