Surprisingly different nicotine bases from different companies can give a completely different vape. Buy small at first and shop around to find what you like. There's actually a 250+ page post somewhere on nicotine comparison spanning the last 5 years or so you could check out. But everyone has their own likes.
I am currently using wizard labs and enjoying it, 100% vg and to me it's really close to smoking a light cigarette. Ordered some vaperstek's source because I read on here it is one of the smoother nic bases around.
I still mix my own flavoring a bit, butdoing small and enjoying unflavored, I believe, has really helped me develop a taste and understanding how to create my own juices to suit me. And now I can flavor under 5% and really taste it.
