If you want one scope for everything and one that you can leave out for extended periods then the 8” would probably be the better fit, especially if you’re comparing it against an 8” Dob.
An 8” when cooled will out perform a 4” on everything. I’ve got a 10” and a 4” but my 4” is used a lot more because the skies don’t usually support the effort of setting up the 10”. Most of what I look at is the moon, planets and open clusters, all of which a 4” does really well at. When it comes o Omega Centauri or other globular clusters, the 10” leaves the 4” for dead. Galaxies? Neither are worthwhile from my backyard hehe
