Best advice for liquid is not to spend too much time on here reading what people like and don't like. Everyone's taste is different. My suggestions is to buy some smaller bottles of several different flavors and strength's then pick what YOU like to get a big bottle. Err on the side of high nic at first, at least 30mg or 36mg. I ordered mostly tobacco flavors at first and like them a lot. Others like sweet and fruity flavors. You will never know until you try.
And most important, get some PG based and some VG based liquids. To me that is one of the single most important factors in vapor production and throat hit (I only have a 510 so I don't know the effect of other atty's...). For me, the VG has better vapor and the PG has better throat hit and stronger flavor. Several folks have PG allergies (my wife for one) so make sure you get a least one bottle of VG stuff in case you can't vape the PG.
