I edit in FCPx every day. I'm constantly learning new things that it can do, but it's organizational tools help me go from loading footage to editing a project in the fastest way possible. Faster than any other editing system. It's a powerful tool that is getting stronger.
I have used Final Cut Pro for over 15 years and it has only gotten better.
Since version 10 we have gotten free updates that include new features, fixes, speed and stability improvements and more at no additional cost or monthly fee.
I highly recommend this product
Final Cut Pro X has been hated on by professionals for years after they revamped the UX. Apple took its sweet time and finally added in professional color grading, LUTs, and HEVC support, and tons of other stuff.
If Apple had this kind of love for their other software, it would be nice.
