Both are tensors with distinct profiles. Tenergy 05 FX (8.4) is soft at 36 degrees, elite Tenergy-based, and rewards touch and dwell for advanced backhand play. Rakza X (8.4) is medium-hard at 47.5 degrees, outstanding grip that overrides incoming spin, and exceptionally linear and predictable for a fast tensor.

Tenergy 05 FX excels at slow-ball spin, flicks, precise backspin serve control, and forgives off-center contact. Rakza X delivers high, safe throw arc on loops and counter-topspins, strong short game with forgiving touch, and versatile on both forehand and backhand. However, Rakza X is heavy at around 69 grams uncut, the topsheet grip can fade after a couple of months, and it is weaker for passive blocking.

Select Tenergy 05 FX for soft dwell-based backhand control and maximum elite performance. Choose Rakza X if you want a grippy, high-spin tensor with a forgiving, linear feel suitable for both wings at mid-range price.
