Should I buy a freestanding closet system or a wall-mounted one?

Renters and people who move often gravitate toward freestanding systems like the VIPEK V5, which reviewers praise for not requiring drilling. Homeowners with permanent setups tend to prefer wall-mounted kits (Rubbermaid, ClosetMaid) because they free up floor space and feel more built-in. The trade-off surfaced repeatedly in home-improvement community threads: freestanding units are easier to install but can wobble or shift; wall-mounted units are stiffer but only as strong as the anchoring.
