Interlock is thicker/denser, more like regular fabric and is pretty stretchy and durable. There are so many different varieties of knit. It will all depend on the quality of the wool. Some is better for toddlers, some is softer but pills more etc. Really it's all personal preference. I like interlock and knit. As far as cost I think it's comparable.

I dry wool the same way all year long. Spin in the washer then lay flat to dry.
