The hammer blades tend to give a flatter finish (like a mower), they do though require more horse power to run. The Y blades are more suited for inter-row mulching (vineyards / orchards),
This is for a couple of reasons. The Y blades are double-sided so when you wear the leading edge out you can turn the blade around. Also the Y blades leave a slightly corrugated finish which allows the mulched matter to break down a lot faster because there is more air flow under the mulched matter.
