LibreOffice may be exploited and used to attack you but a minimal installation keeps the stalkers at bay.

Improved wifi stability with 5.15 update.
Pro Additional themes
No need for external theme sources that may affect how you use your OS. All your favorite distributions can be mimicked.

Cons
Con No one uses it
It's a very niche OS that no one uses.
Con Unfinished
It's still in beta and quite unstable. Making it unsuitable for developing applications of any kind.
Con Language support is terrible

Con Small community
It is important when developing to be familiar with tools that other developers use. You can make any utility in any language you feel like, but if it's in an esoteric language that no one can read targeting a small platform that no one uses, then it was just something you did as a hobbyist, not as a developer.
This is not to say that Haiku isn't a great operating system to hack around on. Just don't delude yourself into thinking you're doing it to get familiar with tools that you need to know to be a better developer.
Con UI quite different to other OSes
Con Can be slow and bloated
May be preferable for new users, but for those who want a minimal system it can be rather slow and comes with many preinstalled applications.
Con Has Wi-Fi issues
Asks for Wi-Fi password continuously.
Con Bad Experience after an update
Had a bad experience after an update and then I gave up.
Con Cannot customize the panel but then you get a more reliable system
A lot of us like to have a power button , restart button and other frequently used apps in our top panel but with Budgie you can’t really customize this but in return you get a great system.
Con It is only completely good if you install it separately rather than on another OS
