The Bluefin (product) is marketed/developed by Superchips (company) so thats the same thing.
'better' is in the eye of the beholder. I would suggest a few 'parameters'
customer base (size)
customer feedback
type of customer profile
distance from you
cost
development time and resource to produce product
updates
VW specific or other makes too?
time in business
dyno plots (both from company and from forums , they differ greatly). shape is as if not more important then ultimate numbers
AirFuelRatio data, EGR temp data etc
ability and type of switching , stock vs mapped mode
adjustable (only REVO can do this)
to name but a few.
[edit: just like to add , Im no expert, just trying to provide an unbiased opinion to allow you to choose for yourself
