I have been using both for many, many years. I now pay for a discounted (40%) plan for the entire suite, which I don't need, but I do use 5 components- Photoshop CC (Creative Cloud), Lightroom (LrC) Lightroom classic, Premiere Pro, and After Effects. Also with the suite I get PDF so I can edit PDFs. I have always mainly edited in Photoshop and only use Lightroom for timelapses since my timelapse software (LRTimelapse5) uses Lightroom for processing.
I do most of my panoramas using 3 or 4 single shots, with a 30% overlap, and process them in Photoshop CC 2021 using Adobe Camera RAW and Bridge. By right clicking on the three or 4 images (or more) in Bridge, you can select all RAW (DNG) images, then CTRL+A (select all) and right click on any image and click MERGE TO PANOROMA. The image appears almost instantly. You can do the same with Lightroom. I tried PTGui trial and never was able to get it right.
For sure, I would get the $9.99/month Photoshop/Lightroom package. There are some many updates (all free) to Photoshop that I love some of the new ones. Google that to learn about them.
