Which snow blower model for x534?

I see there are two models of snow blowers that will fit the x534 a 44in and 47in. Does anyone have experience with either of these blowers on a x500 series tractor? The 47in is a little more expensive but not enough to rule it out. Looking for some pros and cons for each model. The 534 has a hydraulic lift and AWS. Not sure if it matters.
