If you did the Cneifion Arete without gear you certainly won't need any on Clogwyn Y Person, unless you also start by climbing the nose direct which is bordering on V Diff. Clogwyn Y Person is technically easier, less exposed and less polished than the Cneifion Arete.
I use it as my regular descent route when I'm in that area and yes it is easy for a Grade 1 scramble. There are only two sections of proper scrambling, both in gullies, the rest of it is walking. The scrambling isn't that hard even though the ridge looks pretty dramatic from below.
