Hey man!
I think Don's assessment is pretty much spot on.
The answers anyone gives for all 5 categories will always be highly subjective, because everybody's idea of what does and doesn't look nice can potentially be different (as they say, "beauty is in the eye of the beholder"), and what people look for in a tuck can also be different.
Even handling is subjective, because of things such as preferences towards thick/thin cards, stiff/flexible cards, and the amount of slip. Magicians and those who do gambling demos (such as me!) will look for different things in the feel of cards.
Therefore, although this post is going to be long, I'll briefly jot down why I have chosen what I have.
(Other than for the handling section, I'll try and limit my picks to decks which aren't ultra difficult to get hold of just yet, and won't cost an arm and a leg. Also, my picks won't be in any particular order)
Back Design:
(1) LUXX by JP Playing Card Company
The intricate detail and choice of vivid colours for this back design looks both elegant, and spectacular. For what it's worth, it's my favourite back design to date
(2) Aurum by Encarded
Again, the fine detail on this back design is quite incredible, and great use of metalic inks
(3) The Hive by Kings Wild Project
The design clearly takes inspiration from the Tally-Ho design... but it's done in such a way that it cannot be considered a "knock off" in any respect -- it stands tall and shines in its own right. Great work by Brendon and KWP.
Honourable mentions:
- Ornate (all decks) by Midnight Cards and HOPC
- Mana (first edition and third edition) by Erik Mana
Faces:
(1) Egyptian Legends or the Gnostics by LPCC
Yeah, the faces are standard ones... but they have the best recoloured traditional court cards around. They have this awesome shade of gold ink which in turn makes the reds and blues really 'pop' on the courts.
(2) Clipped Wings by Emmanuel Jose
I don't usually care for art decks... but Emmanual's work is an exception because it's in a league of its own. The faces are as unique as they get, and the method used to create the designs is simply excellent. Very original.
(3) Pagan by UUSI
Again, this is more an art deck than a deck for performing gambling slights with... but the custom artwork is really good.
Tuck Box:
(1) Egyptian Legends
This tuck has it all -- foil, embossed foil, a papyrus feel (rather than the), really shiny foil on the interior of the box, thick and sturdy card, a die cut window, and then the usual LPCC traits such as the larger tuck flap, and perforated seal. Furthermore, it looks beautiful.
(2) LUXX
Same plus points as the Egyptian Legends, but without the die cut window. What it does have though, is phenomenal design and excellent use of foil. In terms of look, I think this one is as good as it gets.
(3) Medallions by Theory11
As usual, there's a lot of detail on the tuck of a T11 deck... but this tuck is made using a really soft type of paper which has a luxury feel to it, much like the red monarchs.
Honourable mentions:
- The Hive
- Sultan Republic
- Madison Rounders private reserve.
(Okay, I'm joking about the Rounders private reserve -- only a blank box would be less spectacular. Lol)
Handling:
(1) Sharps
In my opinion, the best handling 'paper feel' deck of cards produced in the last 5 years (at least!). The combination of a well balanced (in terms of flexibility and sturdyness) cardstock combined with the coating that Legends cards use, make these cards unrivalled. The thickness of the cards, I find perfect. This deck will likely remain tough to get hold of... so try and get hold of any deck by EPCC or LPCC which uses their "classic finish" to get a first hand idea of how good these cards handle.
(2) Egyptian Legends
Same thickness and coating as the Sharps... but with a stiffer and longer lasting card stock. For fans and virtually any type of card work, this deck is exceptional. I practice with these every day.
(3) Richard Turner gold standard Bee
In my opinion, the best handling deck USPCC has made. They are made from their top-of-the-line Bee Casino cardstock, and compressed to a lesser thickness... and so they have really nice 'snap' to them and are brilliant for all sleights. Virtually impossible to find these days though.
(4) Fournier 605 -- Lee Asher Signature series
Yes, I've added a 4th one because Lee's deck is that good. A very different feel to any other cards on the market today, and they have a combination of excellent slip and a nice, sturdy cardstock. These are excellent for shuffle work such as riffle stacking. These decks are reputed to be ultra-long lasting. For people are looking for cards that feel different and handle well, I consider the 605s a "must have".
Overall:
(1) Sharps
(2) LUXX
(3) Egyptian Legends
