Mojask,
I guess it would come down to how you intend to use your car, what you want to achieve and your budget.
At about $200 a set TRD leads probably aren't much more expensive than the Genuine Toyota leads.
But, unlike other brands, TRD don't make the claim that their leads will improve power, just that they will deliver the optimum spark under harsh conditions.
Are you ever likely to encounter harsh enough conditions for this to become a factor. Probably not.
I've seen some brands' advertising claiming 5hp or sometimes 5% power gains from using their 8 or 8.5mm leads. I've not seen this demonstrated in practice and would be more than a little sceptical.
