I'm pretty fussy I think. I've been vaping about a year and only have a handful of juices I like. I haven't tried that many really though, I got hacked off fairly early on. I was on hangsen ry4 diy for a long time, was ok, did the job. My main vape now is a very simple diy menthol, maybe a bit boring but there's nothing to dislike about it really. Out of all I've tried the stand out juice for me is tmax snake oil. As for tobacco I found the higher quality ones tend to taste of tobacco leaf rather than a burning roll up, but again fairly limited experience. House of liquid often gets a mention for quality tobaccos but I haven't tried them. I've got some mom and pops tobacco haze steeping so I'll report back when I've tried it.
Welcome btw, you've found the right place
