I have yet to hear anyone say "Opus is really good value for money, a real good economic choice for us". It seems that we're trying to retrofit every possible task with SOTA AI that is still severely lacking in solid reasoning, reliability/dependability, so we throw more money at the problem (cough Opus) in the hopes that it will surpass that barrier of trust.
When my subscription 4.6 is flagging I'll switch over to Corporate API version and run the same prompts and get a noticeably better solution. In the end it's hard to compare nondeterministic systems.
Also, +1. Opus 4.6 is strictly better than 4.5 for me
