I have a tiger cub and it has been a good machine but now it sits in the shop due to buying a new Turf Tiger. It just depends on what you need as to which machine to buy. If you are cutting large lawns then you can not beat the tiger but if the lawns require more finesse then the tiger cat is the way to go. Also a Tiger is going to run you about 10k minimum so that is also a factor. The tiger cat is a commercial mower so durability should not be a factor for you. The Freedom Z is a homeowner version so I would strongly recommend to stay away from it.
