Hi, i´ve never had a luigi´s case, but they look nice and well made. I had a Mr. Zhou for my RD1s, very cheap but made of plastic leather, also is somehow thick, it delivers good protection.
When i got my m8 i considered buying a luigi´s case but it´s way too expensive and as i looked photos i thought it was too thick and bulky.
Loking after i found this Artisan & Artist half case for m8, and so i jumped on it, have to say i´m very happy, it fits perfectly, very thin, precise covering of critical parts as edges, simple elegant design.
The maufacture is superb well stitched nice real leather.
Not that expensive almost 160 plus shipping!
Bye!
