Two models, the numbers decide
Bresser Messier 6" Dobson or Sky-Watcher Skyliner 200P?
Bresser Messier 6" Dobson — 152 mm, €380. Sky-Watcher Skyliner 200P — 200 mm, €545. The same method as everywhere on this site: the numbers first, the verdict from them.
Same family (150–200 mm Dobsonian): what changes between these two is aperture, bulk and price — not character.
Side by side
The Sky-Watcher Skyliner 200P collects 1.7× more light — that is what aperture buys.

The same sky, through both
These circles are simulations, computed from the aperture, the magnification and the sky — indicative, not exact. A real night also depends on the turbulence, your eyes and your experience. Closer to the truth than the photo on the box; still not a promise.
