Couldn’t help myself to order the the black sheath on Black Friday sale. I have the mountain green this year - nice case but that stealthy clean black… can’t beat it.
Also bought the synthesis. The fit is so good, but the back is very prone to marks and scratches- my MagSafe made marks on day 1- It’s kind of annoying…
Others have mentioned, the grip on the sides is better, but at the cost of the back being more slippery. I’ve defaulted back to the sheath- it’s just hard to beat in my opinion. Both great cases, matter of preference.
