How do the two compare?
The main difference is the starting point. An estimating tool starts from drawings. A tender tool starts from the tender pack and its rules.

| Starts from | Drawings, plans and cost data | The tender pack and its rules |

What does estimating software do?
It turns drawings into quantities, and quantities into cost. Choose it if you often measure work yourself.
