What Reddit Says

GitHub Copilot

65% positive

Many developers see Copilot as solid but increasingly overshadowed by Cursor. Praised for reliability and price, criticized for lagging behind in agent capabilities.

“Copilot is reliable and fast. For day-to-day autocomplete it's still great, but Cursor has pulled ahead for complex tasks.”

r/cscareerquestions·412 upvotes

“The $10 price is hard to beat. If you're on a budget and use VS Code, Copilot is still a solid choice.”

r/programming·687 upvotes

Grammarly

74% positive

Grammarly is widely loved for everyday writing improvement. Premium is considered essential by many professionals. GrammarlyGO gets mixed reviews — useful but not a ChatGPT replacement.

“Grammarly Premium is the one subscription I'll never cancel. It catches things I miss in every email, doc, and Slack message. Worth every penny.”

r/productivity·2345 upvotes

“GrammarlyGO is useful for quick rewrites and tone changes but it's not a content generation tool. Don't compare it to Jasper or ChatGPT — different purpose.”
