I’ve recently migrated 75% of my work from FL Studio to Cubase 8.
I don’t regret it, although there are definitely a few things I’d change.
The tools in the key editor seem like they’re out of a program from 2005.
It really slows things down to have to right click and choose from the tools or click on the task bar above instead of just incorporating the main functions into the same tool. (left click is draw, right click is delete and you can adjust length of note without having to change the tool every time, etc) Going back and forth really slows the workflow in my opinion.
Also, the exporting function is a mess. Setting right and left locators? Do people really want to export only a fraction of a song? and if so, why would you not make the entire project as the default.
There’s a few more things that seem odd to me, but those are the main 2 things that pop out after the first few days of tinkering around.
