Given the way these telescopes work, am I better off with a Refracting telescope for terestrial viewing because there is nothing blocking the light?

Which is more an issue for terrestrial viewing, coma or optical aberation?
What about for viewing the moon or the planets?

Plus I assume for looking out my window it will be easier to view with the eyepeice at the back, however more painful for skywatching as If I'm looking up i'll have to be near the ground ? I've read many times people suggesting refractors are better if they have a 90 degree mirror attached. (which makes sense)

Also, is there less maintenance with reflecting scopes?

I'm worried about collimation. If needed do I need to purchase a laser collimator or is there a simpler way to do this.
