deciding on a bucket, first question to ask yourself is what do you a bucket the most for?
since a tooth bucket is best for digging and scrapping up the ground
if you do that most, then that is what to keep
if you mostly use a smooth bucket for smoothing things and moving fill, then>??
BUT you can always ADD a bolt on tooth bar, making the smooth edge intact and if needed, add the tooth bar when needed,
so, if your willing to BUY a tooth bar for the smooth bucket, you can then have two buckets in one,
SO< IMO< the smooth bucket would be what I would keep, and I would sell the other one and use some of the $$ to but a bolt on tooth bar
like one of these
