The Z97 Chipset has better features than the H81 Chipset. Since you have a CPU with a locked multiplier (non-k), you may find the H97 Chipset model a cheaper alternative.
From an official chipset perspective, there are only two differences between Z97 and H97 chipsets. The first is the fact that the Z97 chipset supports CPU overclocking, while the H97 chipset does not. Secondly, the Z97 chipset has the ability to split up the 16 PCI-E lanes from the CPU which allows for SLI/Crossfire video card configurations.
