I went from an 8" GSO Dob to a used 10" Orion Dob. The finderscope on the GSO was an RACI scope whereas the Orion has a non standard straight through. The GSO's RACI was much easier to use. The 10:1 focuser on the GSO was nice too. The Orion doesn't have that higher ratio.
But, everything about about the Orion feels more solidly built. The base feels more dense. I don't Know if it's mdf rather than the GSO's chipboard. The various thumb screws are chrome plated steel. On the GSO they are aluminium. Optically, I think comparing an 8" to a 10" isn't comparing like with like, and I don't have the experience or expertise, so I'm not going to try.
The GSO was cheap, worked well and it had good features.
But it did feel a bit cheap.
