This past year, I have had 100% success with in-ground rooting. But for me, it should really be called "pot-less propagation" because I root the cuttings either in a plastic bag or in a plastic shoe box. When the cuttings go in the ground, they already have roots on them.
Once the cuttings have considerable roots, I plant them directly in the ground (January-February in my area), mixing the native soil with a little but of manure or garden soil.
In my experience, the cuttings grow much more convincingly in the ground as opposed to in pots.
