With a dedicated shaper you will archive layer 7 application recognition and user based traffic shaping inbound and outbound. SUP720 compared to a dedicated box will do just a very basic things sometimes sacrificing other functions (microflow policing and netflow). You could have 2 shapers if you require higher availability. Also optical bypass comes as an option for most vendors.
I also guess that some good news from Cisco in shaping area are comming. Check with your Cisco partner.
