Do you want a pointer or a flusher? Figure that out first, your answer will make the choice pretty obvious.
As far as energy, both breeds you listed can be all over the board. From docile plodder to full bore zoomies.
Find some dog training clubs and go to the retriever and pointer days, check out some dogs and talk to owners.
Look at some litters, meet the sire and dam. Lots of puppy mills out there trying to look like hunting dog kennels.
Personally, I will never own a dog without a docked tail. Much more pleasant in the home.
YMMV
