Telescopes are like many things, there is no perfecy scope to cover all eventualities.
To a large extent the type of scope that suits is determined a combination of factors. Some can be
- what objects are being observed
- is visual use or imaging the main task
- budget
- storage space
- permanent setup or portable
- is it being installed in a observatory
- if portable, how portable and how is it to be transported
- are there existing accessories that it needs to match
That is all I can think of at the moment. Once these questions are considered, you can narrow down the choices a bit. There is an article on this site that discusses some of these issues here
