Cartomizer preference is very subjective, just as is e-juice. My recommendation would be for you to try some carto's from different manufacturers with your favorite juice flavor to see what works best for YOU.
Since I've been vaping for about 9 months now, I have settled in with 99% of my vaping in pyrex cartotanks. I started out using Smoktek dual coils, because that is what came with the tanks. I determined over a couple of months that I was experiencing a fair amount of burnt taste in too many of these, and decided to try the same manufacturer's single coil carto's. What I realized was these gave me the same flavor and vapor that the dual coils provided, yet over time I never experienced the burnt flavor again, and realized longer battery time with the single coils.
Friends here at ECF convinced me to try some Ikenvape Platinum cartos. These have a tendency to be frequently out of stock because of their popularity, and when they returned in stock I got a bunch. I have to say that I like these even more than the Smokteks, a cleaner flavor and they seem to last longer in a cartotank before needing replaced.
I did try some Boge standard size cartos for my couple of standard size tanks. I can't say that I was impressed with either the flavor, longivity, or consistancy. Admittedly, this was the same time as "Bogegate". I've since replaced the standard size Boges with the standard size Ikenvape Platinum carto's.
I used 2.0 ohm resistance with my mechanical mods, and 3.0 ohm resistance for my Provari. I also order all my carto's with laser-drilled carto's for my tanks, as I believe these provide me with carto consistancy, carto to carto, that I wouldn't realize if I punched my own.
For tanks, my favorites have become the
IBTanked - Get Tanked With Us!. I now have 7 of these pyrex tanks, each with their own flavor of e-juice. A high quality, nice-looking, and inexpensive tank that start out at $20 for their simplest tank. I did a review of these tanks here:
