Which is better for road running?

The Saucony Ride 15 TR. It is a neutral road trainer with softer cushioning. The Spin Ultra is a trail shoe with a firmer ride and aggressive outsole that feels harsh on pavement.

Which is better for technical trails?

The Scarpa Spin Ultra. Its Vibram Megagrip outsole and TPU toe cap give grip and protection the Ride 15 TR does not list.

Both use rubber outsoles, but the Spin Ultra's Vibram Megagrip is known for durability on rock. Road miles wear trail lugs faster, so match the shoe to your surface.
