Hi Ames,
Well this is from my experience. I started with cartos first when i began. I used Smoktech and Boge cartos and their carto tank systems. Now i use the Vivi Nova v fate which has wicks.
Pros with cartos IMO: better flavour in a brand new carto vs a brand new wick
Produced a bit more vapour
Cons with cartos: cartos lasted me on average about 4 days to 1 week MAX before i need to change
I experienced WAY more QC issues with them esp ones from Smoktech with a lot in the pack being DOAs
Pros with wick: Seems to me that certain models ie Vivi Nova are easier to rebuild and rewire vs a carto, a tad cheaper too
I found replacement heads of wicks to be at times cheaper than cartos (depends on model and vendor)
98% of the time, my wicks were good out the pack and very rarely any DOAs
Much easier to clean a wick system than a carto and easier refills with a wick tank, no need to boil cartos anymore
A good wick head could last me 3 weeks or so before i need to deep clean or rebuild it
Cons with wick: muted flavour somewhat
There may be much more points but this is all i can come up with now. I like wicks better for convenience and im always on the go. i can live with a slightly muted taste. Some like cartos for flavour, etc. depends on your preference.
