One point to keep in mind with either scope on an EQ mount is that with an SCT, the eyepiece will usually be in a fairly comfortable position, except when pointed close to the zenith (straight up). In these cases, they are litterally a pain in the neck. You can also use a diagonal to move the eyepiece to a better position.
The Newtonian however can have the eyepiece at very uncomfortable locations...you may have to lean right over the scope in some positions or sometimes maybe even get on your hands and knees. Other times it is in a very comfortable position. You can't use a diagonal to move the light into a better position.
