I bought a lb of Magnum back during the hop shortage and used them for a whole slew of styles over a couple years. I thought they were just fine, except maybe for IPA’s or beers where I wanted a more assertive bitterness. The bittering qualities were very mellow.
Last year I bought a pound of Warrior, and I’ve been using them for bittering in a wide range of styles. I’ve enjoyed it in all but my last batch of Patersbier, which is a delicate beer to begin with.
I think both have a pretty unobtrusive bitterness, and the Warrior has been a better hop for the hop-forward styles.
YMMV. Why not pick up an ounce of each and do a split batch, and see for yourself what you like before you commit to a pound?
I am debating about switching it up for my next big bittering purchase, but that’s likely another year in the future.
