Our verdict
How to read a comparison across price tiers this far apart
The bottom of the price range against the top — a pairing rarely put on the same page.
The result is what you would expect: no dropped sessions on standard tasks or in debate.
This comparison is useful for locating a ceiling rather than for choosing a substitute.
When you are deciding whether the cheap option is enough, it helps to know how much headroom exists if it is not.
The gap is most visible in work needing range of voice, such as humour and roleplay.
Not a comparison for picking one, but for measuring where the cheap option runs out.
