The price is what made me switch from Digital Performer. There's a completely FREE version for you to use without time limits. It's really basic and comes with limited features, but at least you have all the time you need to gain experience and feel comfortable before purchasing the full version.
There are 3 different version with different features, but the price range is low compared to other DAW, and every once in a while PreSonus releases good offers to upgrade.
Clean, slick and visually appealing UI. Hundreds of built-in features to speed up your workflow, powerful built-in virtual instruments even for the basic version, smart tools with handy shortcuts, fast and reliable software.
Even with lots of tracks and effect, I never experienced a slow rendering/playback or crash, on a 2011 MacBook Pro.
The amount of options can be overwhelming at first. You can literally do everything you want, and this much freedom can confuse you and loose you inside small options windows or editing panels.
An aspect not directly connected to the software is that, because it's a fairly new DAW, it's hard to find good resources or tutorials online, compared to other products.
Finding a cheap and professional software for home recording and music production.
Having the ability to seamlessly upgrade to a more complete version in case of business necessity.
