Con There is no way to preserve menus and special features
Menus and special features will typically not be included in the output from a handbrake encode. Third party software would need to be used.
Con no linux support for hw acceleration
I know that it is not as high quality, but transcoding terabytes of 1080p videos to h265 without hw support isn't realistic and wont be for a long time
Con Not for 1:1 archiving or true backup use
Most uses of Handbrake are lossy, lossless is possible but it usually entails crazy huge file sizes.
