If you're inexperienced at collimating or the Schmidt cassegrain isn't cooled it won't give sharp images at medium to high power.

The refractor will always give sharp images after half an hour or so, up to whatever magnification the atmosphere allows on a given night. Refractors generally stay in collimation unless they get a sharp bump (during shipping or by being dropped for example).
I have a feeling that you would be happier with a refractor.
