Luke and Ozzy both have a point here:
If you're looking to ride comps on this 'new bike' and when you not at comps your riding on rocks, then by all means the Echo is the better bike. The Inspired in comparison will feel awkward on rocks due to the geometry not being centered around that sort of riding, and it'd weigh more than the Echo too.
Likewise if you mostly ride on the street and enjoy doing something different to just doing static moves and hopping around on the rear wheel then get the Inspired. The Echo will be more difficult to do anything involving a bit of motion (roll-ups, taps, spins, etc..), and the Echo will be more fragile.
To some up: Comps, natural, static moves, lightness = Echo. Street, rolling moves, fun, durability = Inspired.
