Switching to a Purina Rabbit Chow instead of Oxbow??

I am considering switching over from Oxbow Essentials to Purina Rabbit Chow. First off, which type would be alright to switch to? I have seen Purina Rabbit Pro Show listed on the forum but I do not see a product by that exact name. Is it Purina Rabbit Chow Show? If not, which one is acceptable (the actual product name)?



Second, is this an okay switch?



Thanks
