Rarity of one over the other is subjective and Depends on species. these color variants show up more often in aquacultured fish rather than than the non aquacultured species.
Even in aquaculture fish some color variants show more often than others.
A golden tropical or Alligator would be extremely rare but a white one is not that rare, a white Florida would be much more rare than a golden.
Both white and golden Longnosed variants are known from the wild. Golden Shortnosed and spotteds are also known. If I was to say which one is the rarest it would be a white or golden Cuban as none have ever been seen.
Gold gars are generally in the 5,000.00 and up range and comparable to the cost of the more common White tropicals and alligators.
Which would I get.....None of them
I tend to like the natural variability of the "common" fish more than these uncommon ones. I would not mind working with one of the oddball variants but I'm not going to blow $5,000.00 on one. I do not really put my fish on display and do not have the resources to specially raise and spawn them right now so it would make little sense to buy a show fish to not show or propagate. I'm already part of a golden Florida research and spawning project anyhow so do not care to waste my home aquarium and stock tank resources on them.
. I would personally take the White TG out of all of them.
