I had Altimax Arctics on my Golf TDI, and they were excellent. You won't regret that choice.
I bought a used set of 16" WRX wheels with still-good used Blizzaks for the Impreza. I will use those in the winter until they wear out, and then replace them with Altimax Arctics.
By the way, the Altimax Arctics are studdable. Don't bother getting them studded. They're quieter and have better dry road traction without studs. Studs only help on ice. They make things worse in all other conditions.
