You hate using them or installing them? Installing them is a little work, though it really isn't bad at all on a little machine like yours. Nothing like putting chains on a 6 ft high skidder tire. That's some work.
They're cheaper, but studs won't last anywhere near as long. A few seasons perhaps, with the efficacy going down each one. Set of chains should last essentially forever if you're not using the machine on a daily, commercial basis and if you take them off in the summer.
You can (and should) chain up all four tires unless you don't have clearance in the fenders for them.
