It looks quite similar to another PDF reader I used and liked a lot, Foxit. When I decided to look for a reader with more features and that wasn't so expensive, I noticed an important difference. I still think the price is a bit high, but considering the features offered, it was the best option I found.
The interface is very polished and easy to use. The buttons and customization options are visible, which helps a lot in daily use. I'm not a big AI enthusiast, but I find it interesting that this feature is also part of the product.
My main use is for reading and studying; the texts tend to be quite long, and I haven't had any problems with slowness or crashes. So far, all the files I needed to open worked without any issues.
