By spend, Claude ranks higher (#3 versus #6), which shows where more of the measured software budget currently sits. The switching signal adds useful context: after leaving ChatGPT, some companies adopted Claude or ChatGPT.

Use those signals to build a shortlist, then decide against your own workflows and requirements.
