Helped: Supplementing subscription with cheaper model provider.
Got in the way: Claude subscription limits and high API costs.
… Personally, I have a $20/month OpenAI subscription that I supplement with DeepSeek V4.1 Flash (currently using CoralBricks as the provider since it's fast and I'm grandfathered into their $0 cache read pricing). It's working out rather well so far. Even when I use DS all day as my primary model, I only pay about $1/day, which is roughly equivalent to what I pay for the sub anyway (but with no limits).
