GA is more general, however my claim is that the DQ space is the most useful one. E.g. sedenion have little use right now. Also I believe that technically they

Its ultimately up to taste but I often find that I prefer to use the full GA instead of its subalgebras. Often some unexpected beauty or useful result drops out!
