What is the best pdf editor?

What software do you recommend for editing pdf files - mainly changing the text but also changing the layout without messing up the whole document?

I wouldn't want to subscribe to Adobe Acrobat Pro. I see Acrobat Pro 2024 or 2022 recommended but on the official site it's written that they are only 3 year licenses. Does it mean that they will stop working after 3 years expire? I've read that the last true perpetual license is Adobe Acrobat Pro 2020. Can it still be activated and will it continue to work for many years? What is the best site to get such activation key?

What are the best 3rd party alternatives to Adobe Acrobat Pro?
