I went out and bought a whole bunch of canned sardines, each one from a different brand.
I tried them all and they were honestly not very good.
I don't know if it's because I only got the cans with water only, but the deenz we're very DRY and a chore to chew.
Funnily enough, the more expensive cans tastes the worse, and the cheapest one (sourced from Poland) tasted the best.
I also thought the deenz would be more solid, but they fell apart pretty easily.
Also deenz are kinda expensive.
