A Rule Of Thumb
The introduction of computer-guided telescopes has changed Amateur Astronomy fundamentally over the last decade or so. It has brought the ability to easily find targets to those who are not blessed with dark skies.
It is generally agreed that one should obtain the largest scope one can handle, however, if one can't find anything to observe, frustration can soon dampen enthusiasm, and the equipment begins to spend more and more time in storage.
In my short career as an observer, and as a moderator of these forums, I have concluded that there is a general dividing line between spending one's budget mostly on aperture, or forgoing some aperture, and spending a portion of the budget for the technology of the go-to scope.
Before you decide on a scope, stand in the place where you will do most of your observing on a clear, moonless night, and look at the sky. If you can see only a few of the brightest stars, you will have only a few starting points from which to begin your exploration of the heavens, and you will probably soon become lost and frustrated. In this case, Technology is your friend, and you should consider a go-to scope.
If, on the other hand, there are myriads of stars in your view, and you can see the Milky Way, even dimly, stretching overhead, then you can forgo the electronic help, and spend the extra money on larger glass.
Of course, If you just want to get there quick, a go-to is for you, no matter what your conditions are. Personally, I enjoy the hunt, and the satisfaction of star-hopping to a particular target.
If you can see the Milky Way, you don't need go-to. Of course, if you want it, then you need it.
