Used flstudio for (almost) ten years. Bought Reason 4 when it came out because I loved how modular it is compared to FL. Began rewiring the two, but then found 80/90% of the sounds I was using were in Reason, and switching between the two was a pain in the ass so I just decided to work strictly in Reason.

Not to mention I like the work flow SO much more in Reason, a completely subjective opinion of course lol
