There is no silver bullet for project studios IMHO. Both stand alone and software based DAWs have their place. I own and use Roland VS2000 DAW, Mac w/Garageband, and Protools LE. More money than brains I guess.
Each has benefits and downsides:
runs 24 bit so it sounds great. With optional mouse and monitor it works much like a software based DAW with a nice control surface. Very stable with few crashes, limitations on simultaneous effects processing so you need to plan ahead. Reasonably easy to setup, use and get good recordings quickly. I prefer to track live with this and transfer files to the Mac for mixing.
Sounds great, very easy to use, limited effects plugins, reasonably stable as long as you don't draw too many resources. Very intuitive and useful as a project studio/songwriting tool and you can get good demos easily. A good 1st DAW.
If you are doing feature film scores or cutting tracks for Sony, this is what you want. Period. Unlimited capability and mind-numbing complexity. Tons of effects plugins for everything you could imagine and very resource hungry. Compatible with every major recording studio in the US. Downside: Really long learning curve as it is not intuitive. Very heavy on computing power so you need a TON of RAM and fast processors or it will crash... a lot. I am pretty old-school and did a lot of recording on 8T 1/2" tape. I understand analog recording well. Protools is my most capable and least favorite DAW platform. YMMV
