I have subscriptions to both, one for personal and one for work use, and I haven't really come close to hitting the limits since the release of Opus 5.5 and GPT-Sol 6.1, and I'm no longer hitting any of the capability limits I used to experience when using the "mid" tier models, so I don't miss using Astra. It feels like limits at pretty much a solved problem right now, for my level of use.
