Ninja or Trilogy......it´s hard to compare them.
Both of them got their content. And Both of the contents are cool in their own way.
So i would say it depends not on the DVDs itself...it depends on your Skill level and your "style".
Ninja is cool. No doubt. But for me personally ...it´s not my kind of style. I never use the Pass for example....
I like the Buck style more....i think the magic style of the twins is probably the best in the world. This is just an opinion, so don´t be angry with me
But i prefer VISUAL Magic....i don´t like TnRs or these card to wallet things...and i DISLIKE gimmicks.....for me it is important, that cards a changing place/face in front of the spectator or that cards travel invisibly....magic has to be "in your face" for me.
So I definitly prefer the Trilogy.
But as I said...it depends on your skilllevel, too.
If you are new to magic for a couple of days, weeks or months....trilogy WILL be really hard for you. There will come a time, where you regret the 80 bucks
And the Flourishes DVD as well......Ninja don´t even got a flourishing DVD...so if you like to learn flourishes..the Trilogy would be the right choise for you.....wouldnt it?...I dunno.....The Flourishes of Trilogy are HARDCORE! And I MEAN that.
If your new in flourishing and didn´t even catch a short look at The System ...Trilogy will break your Fingers within a few days
There are some Flourishes, like the Erdnase Go Around or the Molecule 4, which will come a little easier but Pandora for example.....
Almost every flourish I was starting to learn in the past...I came through it after .....max. 2 Days...and than i was able to perfect them ....but Pandora for example.....5 Days now....i´m practising like a .......DARNIT! and i´m not even through phase 1 of the Pandora
(plz help me ^^)
But anyway I love the cut.
And I love the Trilogy....it depends on what YOU want to learn and how high your skill level is already set, to decide, which DVD fits to you.
Hope i was able to help ya.
Cheers
