have poles which are MUCH EASIER to set up and pack up as they are essentially two half sets which join at each end
have poles which are much less rigid and do flex a LOT so would not be useful for putting heavier clothes on top, or use in unprotected wind
have better quality materials - more secure clip bases, thicker fabric (230G vs 130G), mesh and floor (210D 3000mm PU vs 200D 2500mm PU)
are wider and taller and have a slightly asymmetric design with rear side slightly lower to allow fitting better in tents with sloping rear doors
but do not have a power cord zipper
are significantly heavier due to the fabric
fasteners have reflective components to see them better at night (need to add these yourself to the Vidalido zips)
supplied with a ground sheet (don't get one with the Vidalido)
large storage areas at each end are elevated rather than just above the tub floor
have a 1P version as well as a 2P version
