For natural eyebrows, hair stroke eyebrows are best.
If they fade later, you can redo or retouch them up again.
Permanent and long lasting colours are not recommended at all, as more work will be required to redo and change to new eyebrow shapes in the forthcoming years.
In the end, I believe you would want to be appear great, natural and energised; thus the cost or ensuring long-lasting embroidery should not be the main deciding factors.
