Sheraz, It totally depends what the requirements of your network are. There are occassions where one has to do to mutual redistribution on two different exit points in a small site, which in turn could connect to a huge L3 MPLS VPN. Thats where tag come in handy. But yeah be wary of the IOS one uses, I have faced an issue where route-map does work really with a few matches, which would work on other IOS.
