I really like smoke2vape. He's got a great personality, a reviewer who, even though he's been doing this for ages is still bumbling his way through the vaping world. He's both humorous and personal, usually only ever telling you how things went for him personally and his experiences with a device / juice.
I also quite like igetcha, he gets newer stuff pretty quick and whilst he does not always seem to really knock anything, he's a good lad! One of the few exceptions to this is his Rev V2.1 review. He really, really hated that thing and you can tell! His production quality is also prob the best around. He's also from good old Uk so I'm a bit biased!
Grimm is classic of course and he's always good for a personal touch on things too. He can at times take a while to get to the point, but then, looking at some of my own text based reviews, I think I'm pretty guilty of that too!
