Let's take the opportunity to look at both boats. I will not be analyzing them since it is obvious that the J122 is a much faster boat and while on the Bluejacket publicity they advertise the boat as a dual boat it it clear that we are not talking about the same races.
The J122 can be a winner anywhere in almost any race, the Bluejacket is more for club racing, or as Americans call it bear can races, that are much more popular in the states than in Europe.
Many bad things have been said about the Bluejacket in the Sailnet, but I like the hull and even if the rigging is not adapted (at all) for racing or performance cruising, I am sure that it will be a fast cruising boat that can even be considered, mainly by american standards, a performance cruiser.
Take a look at the very nice Bluejacket hull:

Happily they seemed to have changed their approach in advertising the boat assuming a much more realistic approach. Initially they have said about the Bluejacket 40:
Delivering a unique combination of exhilarating performance, luxurious accommodations and exceptional quality, the Blue Jacket provides a delightful environment for family vacations and overnight getaways combined with race-winning capability.

to a more modest (and correct) approach in what regards racing ability:
"The hull form and appendages of the Blue Jacket are designed to work in harmony with the sailplan to provide performance that extends daily sailing range and the potential to generate more race trophies....
The design challenge presented was to create a yacht with a performance pedigree, one that could compete effectively in around-the-buoy and offshore races yet provide a level of comfort, build quality and ease of use that would gratify the entire family. "

Nobody is talking anymore about winning races but to compete effectively and about winning trophies. That is better.
The J122 is advertised:
"The J122 no longer needs an introduction. It's a boat that has proven its worth in terms of fast cruising and boasts a series of fine race victories. Its seaworthiness remains unsurpassed, but it seemed important for us to adapt the J122 to the current climate. It's been a tough mission as it's not easy to alter the style of an existing boat. The hull, the deck and the structure are identical. For the rest, together with the Roséo firm, who are renowned designers in the watersports industry, we've given the J122 a thorough review inside and out. ..The J122 E is quite simply more modern and is sure to correspond with the needs of an ever more demanding clientele.
There are several J 122 versions that can suit either the most cruising program or the most regatta program.
The J 122 is a cruising sailboat in which you can expect to find the comfort worthy of the biggest units while it's offering on the deck the most advanced and suitable material for an intensive use.
Many options are available, for the cruising lovers: teak deck, extra water tank, and hood; for the regatta lovers: high modulus carbon mast, boom and carbon steering wheel.
Despite its regattas results, the J 122 remains an easy maneuverable sailboat when crew is reduced thanks to its stability and simplicity."
I would say that both descriptions are now reasonably accurate.
The J122 and the Bluejacket are not pointed to the same market. While the Bluejacket 40 is pointed to what in Europe we call the Luxury market and points to main market cruisers that want a faster boat, the J122 points clearly to performance cruising and racing, enlarging with this interior and the cruising options the scope of cruisers that will look at this boat as a cruising option: experienced sailors that like to cruise fast, like to have a lot of fun sailing and hate to be overtaken. I know of some that fit on this category
Even if the J122 is designed by an American NA, following a long tradition on that type of hulls, it is also as a performance cruising boat much more an European performance cruiser with the interior designed by a very good French interior designer.
Two different concepts in what regards the interior, the american one with lot's of heavy wood everywhere, a very traditional look and much less interior light, the European one light, modern and with lots of light.
I like the Bluejacket interior (even if not for me) but there are two items that are out of place; The stairs, that, under a design and integration point of view, are incredibly bad and the table, Island Packet style. that can work on Island Packets and be a trade mark but here it is just odd and not nicely integrated.

Some recent movies with the Bluejacket 40:
There is not yet any with the new version of the J122 but we can have a look at one with the previous version that has the same sailing performances. Here one competing in a top race last year.
