I've owned PDF X-Change Editor Plus for a couple of years now renewing my maintenance plan with them every year. I rarely if ever edit PDF files but recently I needed to edit a car invoice to add a VIN number and it couldn't do such a simple task. So I tried Adobe Acrobat and it did it easily! I went ahead and purchased a perpetual license for Adobe Acrobat 2020 Standard. Yes it is more expensive but it's not a subscription based license and is much better.
