GeneratePress vs. Kadence: Is Kadence really that good?

Hello, everyone.

I am using WordPress and have tested GeneratePress respond in singing Kadence(including their premium themes and premium block plugins). Both themes are often recommended, so I wanted to dive deeper into their pros and cons.

During the testing process, I found that KadenceBlocks provides a wealth of blocks, and the GenerateBlocks Pro It seems to just add a few extra blocks. A lot of people push GeneratePress, but from my perspective, Kadence seems to offer more functionality and a better user experience. As such, I have a couple questions:

1. What are the core benefits of GeneratePress? Does it have any other unique highlights besides performance and light weight?
2. Is GenerateBlocks Pro powerful enough? Is it more advantageous than KadenceBlocks in some ways?
3. Which is a better WordPress block editor for long-term use, GeneratePress or Kadence?

I may have missed some important factors, so I hope those of you with experience can share your insights and experiences with them. How to choose between these two, thanks!
