Am I falling into the hype train or is Fable 5.1 really this better compared to everything else? Thinking of upgrading to x20 from x5 just for Fable

A Pro user is considering upgrading from x5 to x20, specifically for Fable 5.1, after previously using Opus. They are questioning whether Fable 5.1 is significantly better than other options or if they are just caught up in hype. The user is seeking opinions from those who have tested Fable 5.1 and Opus (4.8 or 5) on similar real tasks to determine if the upgrade is worthwhile.
