I think it migh be harder to heal, because of the more typical horizontal ones don't seem to go as through as much cartilage as mine, if you feel the thickness of the rim of your ear compared to the bit where mine is pierced. But I think it's def worth it, but thats just me, I love mine.
There are many variations of vertical ones, some of which start where my bottom hole is and end on the top of the ear, it all depends of your shape.
Another thing, I can only just get earphones in my ear, so if you were to get one similar, you'd have to think of the positioning of earphones if you use them a lot.
I personally like it a lot more than the typical ones because it's not typical and I've never seen anyone else in person with one like mine.
Oh yeah, and another thing, my mum was worried that someone could easily rip it out, but I think mine would be a lot harder to do that with than one on the edge because A - it's further in my ear and B - Its harder to grab onto.
