The B85 is an original Haswell board iirc. That means if you plan on purchasing a Haswell Refresh CPU, it might need a bios update before it will work with the CPU.
Other than that the H97 chipset should offer some more features, such as more Sata III or USB3 ports, maybe a better PCI slot layout. I'd say look for that. The quality difference will be negligible and a performance difference is non-existent.
Or get the one with the colour scheme that you like best/ best suits your other components.
