I've put together an illustrated review of PSP's brush engine. As you can tell, an engine that was built at the time when tablets were only just becoming popular, just isn't relevant anymore. Under "General program preferences, you can even spot the outdated phrase: "Disable pressure support for puck-type pointing devices"...
Note: I decided to compare PSP not only to Photoshop, but also to Open Canvas 1.1, which is a single 1 MB .EXE file.
Get with the times, man...
