What telescope is better?

The Meade 8" f/6 LightBridge Truss-Type Dobsonian DX or the Orion Skyquest XT8 Dobsonian? Please answer only if you know something about telescopes...

for a 8" reflector, I would go with the solid tube design.
if you are talking a 12"-16" scope, then I would prefer the trusses.

Description

The Sky-Watcher 10 DOB: The Sweet-Spot for Aperture and Value!This is a big friendly horse of a telescope you can ride off into the sunset with and then thrill to well resolved celestial views when twilight fades. The SW 10" DOB is a very satisfying telescope to own an instrument that will provide a lifetime of continuing exploration of the heavens. This telescope will hit the sweet-spot for many amateurs providing all the capability and value you are seeking in a large aperture telescope. Sky-Watcher's revolutionary truss-support concept allows the optical tube's front and back cells to collapse together aligning on the truss support rods which can then be locked down for easy and secure telescope transport. This one piece low-hassle OTA design is mechanically simple and results in a large aperture telescope that can be reasonably handled and transported by one individual. This innovation gives Sky-Watcher users tremendous functional ease-of-transportability. Viewing with the SW 10"—Size Does MatterIn viewing deep-space aperture matters—big time! With this telescope you have tremendous light gathering power. Prominent deep-space objects seen well in an 8" SW DOB such as diffuse emission nebulae in the summer sky like the Lagoon (M8) Trifid (M20) and Swan (M17); the stunning globular star clusters M13 and M92 in Constellation Hercules; the awesome winter sky's Great Orion Nebula (M42) in Constellation Orion and our enormous local galaxy group companion the Andromeda Galaxy (M31) in Constellation Andromeda to name a very few will appear more spectacular brilliant and wider in extension in a SW 10" DOB.Many challenging objects for an 8" aperture now come into their own with the SW 10" DOB: the planetary nebula the Crab (M1) a supernova remnant requires a 10" aperture to truly begin to appreciate the several subtle gaseous filamentary structures. M33 the spiral galaxy in Constellation Triangulum exhibits significantly more open arm structure.

Description

This book tells how you can build a state-of-the-art Dobsonian telescope using readily available materials and supplies. Every step of construction is detailedin photographs and diagrams, and the underlying ideas are carefully explained. As a result of this three-year collaboration between authors David Kriege and Richard Berry, experienced and well-known telescope makers, you now have the opportunity to build a high-performance telescope from 14 inches to 40 inches aperture based on the thoroughly tested designs described in this book. The Dobsonian telescope takes its name from the astronomer/philosopher John Dobson, who introduced the concept of inexpensive, large-aperture telescopes to astronomy. Amateur astronomers at the time were so amazed that a telescope builtfrom simple, inexpensive materials performed so well that they could hardly believe their eyes. As home-built Dobsonians started showing up at star parties across the nation and people saw what Dobsonians could do, the word spread. In just a few years, the Dobsonian revolution swept the world. Since those early telescopes, Dobsonians have improved dramatically. An entire generation of amateur telescope makers contributed their best insights and refinements to Dobson's original design. Today's Dobsonians are larger, lighter,and more precise than ever before. For example, it is possible to build a telescope of 20 inches aperture that is compact enough to transp
