another consideration is money. How many music apps can you afford to keep current?

When RB first emerged, I had already invested a lot of time in learning Sonar up to version 6.0. So,
For a while I used it because I already HAD it, and I understood it. But keep in mind that all sequencers share about 90% of the same feature set. I decided it didn't make sense to keep paying for multiple upgrades every year for several programs that are very very similar. RB keeps improving, so with every upgrade I get a more robust DAW, whereas Sonar 6 stays on my computer, but never advances.

Another consideration is "which features do you use most?" Sonar has tons of features I never used, but RBs feature set is 100% usable to me. Other people here use tempo locking, so they aren't ready to abandon their other DAW because that feature is provided. But I don't use tempo locking, so RB is not deficient for my needs

Another consideration is: "which software implements the features i use most in a way that makes sense to me?" I'M a guy who mostly uses software to make covers. There are key steps in my procedure that are VERY difficult to do in Sonar and very EASY to do in RB. For example, the ability to bring a cover song directly into RB, extract the chords and map its tempo to the songs tempo is priceless to me. Likewise, the ability to quickly lay down tracks for instruments I don't even play is priceless. Sonar doesn't have that feature at ANY level of difficulty
