Portable vs. in-ground basketball hoop — which should I buy?

Across r/Basketball and r/BuyItForLife threads, the consensus is that in-ground hoops with tempered glass or polycarbonate backboards and 5"+ poles deliver dramatically better rebound and stability and tend to last 15-20+ years. Portable hoops win on flexibility (renters, shared driveways, kids who want to lower the rim) but reviewers consistently mention wobble, base leaks and weather damage over time. If you own the home and have a flat slab, in-ground is the buy-it-for-life pick.
