I had the V Collection before getting Logic. I personally like fooling myself having a make-believe software version of a synth I know but can't afford. To the point I hardly ever use the Advanced panel with the extra features added by Arturia, and keep it as faithful as possible to the real thing. So as good as Logic's synths may sound, they don't fill that particular gap for me.
Having said that, in the case of electric pianos and organs I do prefer the sound of Logic's offerings.
For beginners, getting the full collection in one chock-full can be a little overwhelming. I've had guys asking things like "which one do I use for bass?". Like they're not aware any one of those synths was all you could afford back in the day and learned them inside and out to squeeze every possible sound out of them.
I always give them the same advice: make a full song for each one of them, using just the one per song to get all the sounds, and soon you'll get a feel for their particular strengths and weaknesses + it's a good exercise to get to know them.
