Are Electronic Cigarettes Advisable Over Regular Cigarettes?
you asked...."better".....
Detailed Answer:
well....there are some qualifications, if it was ONE cigarette a week and switching to a heavy E cig habit, then no, but mostly it is people switching to a lower number of inhales of e cigs.
Several points of why it is better. Let us start with it is far easier to go off of e cigs than regular cigarettes. I have successfully said to people who wanted to quit to start (that day) by switching to e cigs. Cigarette addiction is different from all others: it is based on how rotten you feel with withdrawal far more than the pleasure you get from being on them. You can dial down the nicotine with e cigs very very gradually and have minimal withdrawal. With cigarettes studies show that if you go from 20 to 10 cigs, you just suck them down to the filter to stay at the same amount of nicotine with the lower number.
reviews say, "yeah, they probably help you to quit"

Then, there is probably less crap in the e cigarettes and this means less lung problems. Less.
"Studies show that EC vapors contain far less carcinogenic particles than TC smoke" This is going to get much better when the ethylene glycol is changed to water.

This is pretty easy to theoretically demonstrate with seeing how much crap you get out of cigs vs e cigs (much less). How much this crap would kill cells in a dish (much less). how much crap goes out in the air (much less). How much reaction to crap people have after one of each (heck, WHITE COUNT goes up with a cigarette...I did not know that until this question!). The preliminary data strongly show e cigs are less toxic. But then, preliminary data showed Hillary would win. In both cases you need to see the actual results and cancers take 10 years to show up. so ... we don't totally know yet, but it really really seems like they are a LOT better than regular cigarettes.
better on blood pressure and better on quitting
