## The answer, as recorded

Asked on 2026-10-04 through Claude (Anthropic) with web search (model claude-opus-5).

> ## The short answer
> 
> There's no single "best" - the right pick splits mainly on **what you build** (residential vs. commercial vs. heavy civil) and **whether you want takeoff and estimating in one tool**. Here's who I'd actually name, in order:
> 
> ### 1. STACK - the safest default for most firms
> Cloud-based, takeoff and estimating in one place, so measured quantities flow straight into priced line items without re-entry. Works for GCs and specialty trades alike, nothing to install, easy to put multiple estimators on the same set of plans. This is my first recommendation if you don't have a strong reason to pick something else.

> 
> ### 2. Sage Estimating - commercial GCs who need a deep, standardized cost database
> The long-standing choice when you're bidding real commercial work and want assemblies, crew-based pricing, and a cost library your whole team estimates from consistently. Heavier to set up than STACK, but it scales and ties into accounting. ([dupple.com](https://dupple.com/learn/b
