Depends on what you want/willing to wait for. The weathering on this seems thick if you'd rather have a shiny Mando. But you'll also likely never see the Beskar spear as an accessory again.
And who knows what he'll look like in S3, as I doubt they're gonna make a BOBF version.. My guess is, once he goes to Mandalore he'll probably at some point have a new painted armor look over the current raw metal.
I'm torn too. I skipped the previous waiting for this shiny, but unsure like many due to the excessive weathering. But we may not get another Mando in this look.
