Thank you for your assistance, @simaudio !!!
Here’s my thoughts:
The synths, to my ears (i´m no expert), sounds really good. I really liked the Moog, Juno, Prophet, DX7 and CS-80. Was very quick to get an sound that i like and a lot of fun to tweak - since the GUI is very good (and have high resolution, resizable too). For an non-expert like me, the fact that the instruments look like its originals and have the original name also helps in the “synth education” side. 
I loved the Electric Pianos (all of them). Really good out of the box and really authentic (at least the Rhodes and Wurli that i know really well the “real thing”). Its so fun to play an instrument that sounds and feels real. Was an good surprise and, even with the fact that with some tweaking you can get a great sound from all Native Instruments Keys, at least to my taste, Arturia has done a better job here.
The Piano (i mean, PianoS - there´s 12 of them in one instrument) have a lot of love and hate around the internet, but i love it. It’s the best Piano VST I’ve ever played (and i´ve played some, believe in me). The funny thing is that isn’t sample based. In a famous forum, people who were saying that Pianoteq is the best piano to date, were the same ones who chose Arturia´s Piano over Pianoteq on a blind test. Since Native Instruments Pianos (and some others) doesn’t give me instant gratification, i´ll choose Arturia again. I don’t understand why this Piano is not an constant on Piano VSTi´s discussions.
On top of that, NKS ready, fast loading times (at least for me and i don’t have an super machine), organized presets and everything at one place (with the included Analog Lab). Just one click to change an instrument and tweak fully.
The weakest link for me are the organs. Especially the B3.
Conclusion: I´ll buy it, but not now. I heard that they make an annual sale every january with the same 50% off.
Since Black Friday is coming, i´ll save money for that and ,in 2 months, i´ll buy Arturia V Collection .
