There is no answer, because, as framed, there is no question.
I'm a guitar player and violin owner, and the violin has three things that make violin harder.
1) Lack of frets. I am sure that your ears and brain don't really know what in tune is, and frets mean that you can get an electronic box to figure that out for you, while violin means you need to know the right notes. You will sound horrible at first.
2) The bow. The wonderful sustain from violins come from bows, and that is a skill. I bow like I pick, very percussive and choppy and not singing.
3) Ergonomics. You hold a violin with your chin. You feel like you want to hold it with your hand, but that leaves you stuck in one position.
If it was just zero-to-song, guitar is much easier, but that doesn't mean "don't play violin". Violin is mostly a lead instrument, so you can't really sing and accompany yourself like you can with guitar. But, don't you know, they make a beautiful sound.
