URGENT-Optimal Code Assistant right now? non-Cursor (context + code quality)

Hello,

I Was wondering if someone could help me with options for my project.

I am relatively a beginner but learned alot using cursor/chat gpt last few months.

Cursor really went off the rails for me last couple days (almost useless and destroying my code/designed tools) so I need a better option and willing to invest the money to help finish my project.

I had actually decided to try Chat gpt Pro for a month but hardly had time to use/doesn't have code interpretor and asked for a refund which I kind of regret as I didn't take advantage of the extended tokens which probably could've really helped (wasted too much time debugging on Cursor)

I have learned to break down my project into modular parts however I find I still need to give alot of context as a true beginner.

I need to finish off parts of this within a couple days, could anyone share my best options for a true assistant + high quality code balance?

Does it make sense to subscribe straight to anthropic Claude (28$ a month) for actual 3.7? (not cursor version which is a mess) II also hear about "Claude code" is this an extension with it to Visual studio code, is that extra cost?

My problem is because im a beginner I do need a relatively straightforward integrated AI assistant setup, as long as I have a good agent/ability to provide lots of context I can usually manage through building slowly.

I hear alot about Aider, already tried Cursor, I think there is a new one called Augment Code? Also really haven't explored DeepSeek paid options.

I'm basically seeking advice/ input from anyone who could recommend best option for my case as all these tools are constantly changing/upgrading.

I will invest money but I just want to pick the best option that will also give high quality code, i think what im regretting most with canceling the Pro was all the context and tokens I could've had access to for this.

My mind is thinking if Sonnet 3.7 works way better straight through Anthropic this might be the best option but not sure if it does as good with context/deep understanding of context/mapping a architectural plan?

I'm looking for highest quality + optimal assistance as this is only for a few days and urgent.

I really appreciate any input or feedback thank you
