Tension pole, over-the-showerhead, adhesive, or suction cup — which type lasts longest?

Across the reviewers we read, anodized aluminum and stainless-steel tension-pole caddies draw the most positive long-term comments on r/BuyItForLife and r/DIY, while suction-cup designs are the most frequently criticized for failing over time as the rubber degrades. Adhesive caddies sit in the middle: verified-purchase reviewers report multi-year success when the tile is cleaned with alcohol first, but failures when surfaces are textured or porous.
