Are you more likely to get perfectly flat pieces with the Ecocast?

You only need Eco cast or ground plate for critical surfaces like bearing plates or Z axis etc that require parallel surfaces. Gantry sides are not so critical in terms that they need to be perfectly flat or parallel surfaces. Thou I find the difference in prices isn't always huge and the cast plate is so much nicer to work with so I just use it for everything.
