What is a tool you use everyday but cringe when you have to open them? For me, Excel and Adobe PDF. Replacement recs?

Since I moved to Google workspace, I've adopted google sheets. It's not perfect, but for the most part, I can do everything I need in there with ease. But I still work with organizations that use Excel. And yes, I always try to import it into google sheets first, but sometimes, when they are complex files with macros etc, I am forced to use Excel and I suffer trying to switch between google sheets and excel and finding the tools I need to do simple basic things! Is there anything out there that bridges the gap with a clean, simple interface?

As for Adobe Acrobat, I can't begin to list all my frustrations with it. There are so many different tools (see screenshot here. If you click View More at the bottom there, I counted, and there are 29 different tools...) What is the difference between edit, comment, organize, fill & sign etc? They are all EDITING the document. Why can't I just do all the things I want to do in the same interface?!

I use different tools for my personal PDF needs but I'm hoping to get recs for reliable PDF tools I can use in the professional setting (e.g. for an occasional signature I need to get request, I don't want to use an unknown, not trusted product that might not make it to my end user).

I've love to

1) hear recommended products to replace these tools (or maybe someone wants to tackle the issue and build one?!)

2) hear what everyday tools you use but cringe every time you open them (maybe someone in the community can help!)
