I have both the Apple silicone and the Sheath. They provide similar levels of protection in my opinion with the Sheath providing slightly less. The Sheath solves your issue with lint and being too grippy though. The coating is kind of pebbled making it easy to grip but not sticky grippy.
Sheath also protects bottom edge.
Interestingly enough, i'm finding my 2nd generation Sheath for XS (proper cutouts on bottom) is grippier than my 1st gen one. not that its hugely different, and maybe i'll have to compare after several weeks, but i do feel the 2nd one is slightly grippier.
