Gave up smoking just about a year ago and have been on the vapes since. Tried a rake a different flavours, went off tobacco pretty rapidly. I am using a zenith tank on an innokin Kroma-a, MTL only @ 17W. I found the darker dessert style vapes caused coils to burn out really quickly, like in a day or two, however I was always changing flavours and had not settled on anything I would call an all day vape. Eventually started on the icy fruit flavours as they tended to be clear and that seemed to make the coils last much longer.
Current all day vape is
Yeti (formerly Dr. Frost) – Watermelon Ice. I have been on this exclusively for the past 3 months and it just works for me, the coils last at least a week, the flavour is not heavy and sickly, and I was surprised to like the ice as I had no interest in menthol.
I tried some Crusher ones when there was no Dr Frost and I was really disappointed as they had that gross background flavour that just completely put me off. The watermelon one was ok, but the mixed berries was particularly bad - I binned that one.
Some other ones I have tried and liked - but not quite suitable for all day vapes:
Tuxedo Like a sir: one of the few tobacco ones that I enjoyed.
Tuxedo Italian: Coffee and almonds, nice but heavy on the coils and has an overpowering flavour. Both of these vapes left quite a lingering cloud behind and would be noticeable on clothes/fabric as a sticky kind of feel if vaping heavily.
Black Flag Risen Enriched by Five Pawns: Really unusual flavour. Too expensive for all day vaping and probably a bit complex for it anyway. Nice tobacco, also some truffle and other stuff in there. Have had nothing like it since but would buy a bottle if I saw it.
Lux Butterscotch chocolate espresso: More like eating than vaping, really very sweet. I found it too much by itself, after a few blasts its very cloying. I mixed it with some other vapes and it was ok like that.
Beard X no 00: This was my all day vape for a while and its a great flavour for an ex smoker who likes coffee, but it was a hoor with the coils - the worst of the lot. I thought I had a bad batch but no, it was the liquid. Its 80% VG so probably just too much for an MTL machine.
I personally found any of the hale vapes or the others you can buy in newsagents gave me fits of coughs. I think it was the high PG to VG ratio in them, didnt suit me.
