Besides being an IEEE standard, does 802.1w switch over faster ( > 2 secs) than the Uplink Fast, Backbone Fast .. ? What other benefits that this standard offers in a High Availability environment?

Thanks

The most important selling point of 802.1w is that it's a standard and so compatible with other vendor products. If you are happy with PVST coupled with Uplink Fast, Backbone Fast for faster convergence, I dont see any reason to switch to MST/RSTP. Also note that not all Cisco switches support MST/RSTP
