I did years ago and I was impressed by the overall quality, it is a very powerful DAW. Excellent native plugins too. Second to none. And it was rock stable on Linux/Wine. Three big problems though:
1. I really don't like its workflow. It is very obviously made for repetitive music, where you create short clips and reuse them over and over. The concept of one long clip per instrument is almost non-existent. It can be done, but it's awkward. It's not designed for that.
2. Managing plugins with it is a nightmare. Rescanning takes a long time and you will find yourself rescanning your entire colllection over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over and over... unless you never add any new plugins. You can't remove all directories from the scanning and scan one directory with a new plugin like I always do in Waveform. If you do that, FL Studio will find the new one and forget all the others. If you add a new directory and keep the old ones, the old ones will be rescanned all over again. Dumb like a box of rocks.
3. It's very expensive.
