I do not believe gateway protocol is important when using called party number transformations although to date I have only used them with MGCP.
The selection of the gateway protocol depends upon whether you need particular features of either - e.g. H.323 provides call routing intelligence and number manipulation on the gateway, MGCP is simpler and allows more granular control of ports within route groups in CCM).
If everything is equal I tend to prefer H.323 but that is because I am from a routing and switching background and prefer doing things in IOS.
