Better as in you'll be happier with the end product after a dozen iterations and two dozen small tweaks? Sure.

I think people underestimate what a time investment building your own tool that's of at least medium complexity is, though. It might be worth it if it's something you'll use regularly for a long time, but I don't foresee it being the norm. Even assuming no bugs ever or no performance issues ever and all the architectural decisions made were appropriate (pretty far from current reality), merely describing what you want and how it should behave and look like is a long process, and one that isn't all that enjoyable once you go through it once or twice already.

The existing software that has been around for several years and you kinda dislike is probably much more reliable than your own homebrew, too. Doesn't matter in some cases, matters hugely in others. Learning that your custom video gallery organizer just vanished half your family videos probably isn't very enjoyable, but at least it's easy to recognize it happening. Something more abstract like CAD or 3d printing slicer, ehhh...
