Vapes provide a significantly different high. As other people have already stated, vaping releases more THC and less CBD, meaning less body high, but a more psychedelic heady kind of high.
The biggest problem I've found among people who are new to vaporizing is that they try to hit it as they would a piece. If your vape has a fan set it to low and hit it at that speed, if it doesn't have a fan just inhale as slowly as possible, this way you'll actually be getting large hits.
Personally I prefer the high I get from my vape, the only thing that's compared was one of my bongs, but unfortunately somebody dropped it and both of the percs snapped at their bases and the elbow broke off, but I digress. If you smoke for the body high and "to get fucked up," you probably won't enjoy the vape as much; if you like shrooms, LSD, and prefer the psychedelic aspect of weed you'll probably enjoy the vape.
