Comparison
The Sky-Watcher Quattro 300P is the clear winner for most amateur astronomers. This 12-inch Newtonian significantly outperforms the 10" Collapsible Dobsonian across nearly every category that matters; it scores 64 overall versus 30, with particular strengths in astrophotography, planetary viewing, and deep sky observation.
The single most important differentiator is optical capability; the Quattro's larger aperture and superior design deliver noticeably brighter, sharper views of faint galaxies and nebulae while its equatorial mount and f/4 focal ratio make it far more suitable for serious astrophotography than the Dobsonian's basic alt-azimuth design. The 10" Collapsible Dobsonian should only appeal to observers prioritizing ease of transport and backyard storage; its modest portability advantage becomes irrelevant given its poor performance scores.
The Sky-Watcher Quattro 300P belongs with anyone pursuing deep sky observation, planetary detail, or astrophotography despite requiring more setup space and effort. For the typical amateur astronomer with modest transportation constraints, the Quattro's superior optical performance and moderate $800 price advantage make it the obvious choice.
