Disclaimer: I do not own these saws, but I do own two Delta 14" saws and a 'proper' resaw bandsaw.

If I had to pick between these two particular saws, I would pick the G0555 and save the $300-odd bucks because IMO the stated improvements don't justify the spend.

I would value the larger table and larger motor, but if you read the 'award' excerpts on Griz's own page for the 0555, none have found these things lacking in the 0555.

The other changes would have little value to me because again, the 0555 is not lacking in these areas (stand doesn't wobble, wheels don't break, the normal fence resaws fine, a light is <$20).

The 0555x seems to be 'gilding the lily' as they say.
