Both Claude and ChatGPT are capable assistants, and both improve quickly. For most businesses the honest answer is that the setup, training and fit with your existing tools matter more than which model tops this month's leaderboard. Here is how to choose sensibly.
Why benchmarks are the wrong place to start
Public benchmarks change constantly and measure things that may have little to do with your work. A model that scores slightly higher on a reasoning test will not help if your team does not use it, or if it cannot reach the documents and tools your work depends on.
A better test is your own work. Take five real tasks your team does every week and try them in both tools, with the same context and instructions. Judge the results the way you would judge a colleague's work.
Where Claude often stands out
In the work we do with clients, Claude tends to be a strong fit when the job involves:
- careful, well-structured writing that needs little editing
- reading and analysing long documents, contracts, reports or data
- following detailed instructions and house style consistently
- repeatable team processes, using Projects and Skills
- software development, through Claude Code
Questions that matter more than the model
- Which tools does your business already live in? Deep integration with your email, documents and systems can outweigh small quality differences.
- What admin and data controls do you need, and which plans provide them?
- Can you give the assistant your business knowledge in a way the whole team shares?
- What does your team prefer after a fair trial on real tasks?
- What will it cost per person at the level of use you expect?
You do not have to pick only one
Some businesses standardise on one assistant for most work and keep another for specific tasks. That is fine, as long as each tool is on a business plan, covered by your policy and set up properly. What causes problems is unmanaged use of several tools on personal accounts.12
Our view
We specialise in Claude because, for the writing, analysis and process work most businesses run on, it is consistently one of the strongest options, and features like Projects, Skills and connectors make it straightforward to tailor to a business. But we are not here to sell licences. If a different tool suits you better, we will tell you.345
