When you say "jacket", you mean plated?
True jacketed bullets are considerably more expensive than poly coated, while plated and coated are similarly priced.
I much prefer poly (Precision, Bear Creek) to plated (Rainier), but do use both.
For practical competition, some dislike the additional smoke of poly coated bullets, compared to jacketed or plated, but the plated bullets that I've used have been extremely soft, being easily distorted by just the bullet seating and crimping processes, while poly bullets are harder, and they leave next to nothing in the bore in the way of residue.
