What is the best brand of canned cat food??

What brand/kind of cat food should we get my cat??My cat is 17 years old and the vet said that we need to switch her to senior canned cat food. She has ate dry food before and we usually buy good life recipie. There are just so many choices of canned cat food, but what is the best for the price?? We dont want to feed our cat the most expensive food. Also do they even make senior canned cat food?? Thanks!!
