Pioneer is better in the way that they actively seek to promote to the point of evangelizing and support the founders of what they classify as promising up-starts (top 1% or otherwise) using metrics they measure. Startup school is more hands-off than Pioneer. The latter gamifies building a product that might motivate people and create a sense of achievement. The former is more on-your-own kind of a thing. That said, I haven't been through a Pioneer program myself but know founders who have and liked it.
