Klin vs. Allnodes staking

Is my understanding between Klin and Allnodes accurate?

Klin hold withdrawal keys but not validator keys? Allnodes holds your validator keys but not withdrawal keys.

Also Klin is easier since it interacts directly with ledger vs Allnodes needs the validator keys to be generated?

And Allnodes is flat fee $15 vs. 8% of rewards with Klin

Any other points I’m missing when comparing the two? Or if there are better options for solo staking (without me getting my own hardware)
