I have a lot (ALOT ) of friends who produce music, and 3 years of experience in music production. In the past, we haven't been too fast to recommend fl studio (as seems highly common), and I've rather liked reason due to the oh so high quality soft synths, but since fl studio 12, we'd recommend fl studio wholeheartedly, and if you can afford the signature bundle, it'll be especially worth it. However, finding a pair of production headphones is equally important in my opinion. If you had to choose between more features in fl studio and a pair of production headphones, I'd recommend the headphones :3
fl studio 12 producer edition > headphones (ath m50x recommended) > signature bundle ^~^
P.S. Since you're using logic, your computer is probably an apple. Fl studio doesn't run so well on my non-windows machines, so maybe try reason if you're not going to use windows. Besides this, you might want to look into getting new plugins or perhaps new samples instead of a new daw. It might be that you just need new sounds and not a new interface.
