As somebody who has a strong attachment to SBD, the prices on the internal market are often slightly better than externally (if you ignore Upbit where the token price is just a completely ficticious number). That's for switching SBD to STEEM.

The difference is marginal though and the internal market also has the benefit of being "no fees.

P.S. Canonical URLs and steemit.com's handling of 'meta' information is a great big pain in the buttocks.
