Sorry: but there;s quite a few people who would disagree with you about the intellicig EVOlution! .....me, for one!
I have no experience of the Blu, but I know they haven't had very good reports.
The 510 is the
ecig of choice at the moment and gets recommended to everyone.... no matter what they want from an e-cig.
I personally prefer my EVO to the 510. I find the 510 kills flavour, has a slightly burned taste, is too fat for my liking, and I don't like using a manual battery all the time (the autos for the 510 are generaly regarded as terrible). Most people praise it because they like a manual battery and they want the hit it gives (although personally, do not find that much diference in hit and vapour production between an EVO and a 510, and the EVO certainly gives more hit and vapour than I ever had from cigarettes).
The EVO is also an extremely reliable e-cig.
Basically, to the OP, you need to decide what it is you want from an e-cig an look at which model provides what you need. Now, it may well be that the 510 is the e-cig for you, but find out what are the pros and cons of each e-cig before you make your mind up, because, as I said, at the moment everyone is recommending the 510 to everybody - no matter what it is they are looking for in a e-cig! ... it is NOT all things to all people!
