So i'm wondering if the origin 8 chainring is just crap and not round at all? Would the sugino mess chainring be a good upgrade for me or are there better options out there (my cranks are 130bcd).

That's normal. Even high end stuff might not give you a smaller variation between loose and tight. It's random.
My Dura ace track crank/chainring/bb/kmc x10sl + phil wood cog on phil wood hub has no detectable variation in chain tension as you spin it.
