Just to add an alternative perspective having flown both the sky couch and PE recently. I would prefer sky couch. Despite being taller than you I can sleep with my legs bent, and would much rather sleep flat (Sky Couch) compared to reclined (PE). Sky couch is also very comfortable for me to sit, back against side of plane, legs fully outstretched. This is ideal for using laptop or iPad I found, and overall in sky couch you have a much larger personal space than in PE. As mentioned, its also easy to move out as never anyone next to you, and also can have a "separate" seat for food if you want. I don't eat much onboard so the "nicer" PE food doesn't outweigh the, for me, nicer seating experience.
