Hi and welcome to the forum.
I would say the VC would be a little difficult for beginners, but not overly. It would take a bit more study than some of the other synths around is all.
The TI does have less menu navigation, but it also seems to have many more options.
The Virus would be a bit to get your head around at first, and having access to so many user patches would create a lazy attitude to creating your own if you were having trouble learning the basics.
