swaybars: heat vs cold treated

[00firebird]

so i was looking at different swaybars available on the market for our cars and found that different companies were both claiming one being the better method over the other. here are their marketing claims

cold

Made from cold formed steel to better resist torsional fatigue and retain their "memory" far longer than conventional hot formed bars.

hot

Most aftermarket anti-sway bars are cold-bent, making them weaker at the bends, and more vulnerable to shape alteration.

interesting? which one is better?
