I started out vaping with cheap 808D cartos and thought is was fine. I didn't like refilling so often, so I went on to the Smoktech 3.5 tanks. That was a disaster, as I couldn't get the juice to regularly flow into the carto without sucking my brains out. At the time, I hadn't learned about the whole carto punching thing. I moved on from there and my next venture was the Ego Mega DCC, which at first I thought was all I needed. After the decline of the performance after a couple of refills, I was looking again. Next came the Stardusts (which my wife still uses for work because they're convenient). I liked them at first, but started to feel that they muted the flavor. In the process of ordering things to try, I had ordered a box of the Boge 2.0 cartos...this was my next stop after the Stardusts. I was instantly in vape heaven with these. I loved the flavor, the vape was smooth for me, and I was happy. I found it ironic that after all the stuff I had ordered and tried, I was basically right back where I started with a simple carto. Problem was, now I was back to refilling frequently. Ugh! After learning more, I decided to go back and try tanks, but taking the Boge 2.0s with me...and I haven't looked back. I use standard length Boge 2.0 cartos in Bella Tanks, just got a Phiniac tank, and Smoktech also makes a 4.5ml tank that's not commonly sold with vendors. That one allows good volume, but still utilizing the standard length carto. I am very happy with this setup. I have gotten in on some good carto co-ops, so each carto only costs just under $.80. It's cost effective to use a carto for a week, chuck it in the trash, and slap a new one in. There's no cleanup, no maintenance, and I couldn't be happier with the vape.
The point to all this is that you just need to find what works best for you, hopefully without breaking the bank in the process. If you happen to pick up a Boge carto (or another type known for performance) and love the vape, the tank part will be easy to figure out...especially with this board. In the early days, I was all excited about the whole process of maintaining the products we were using. My wife would tell you, I was cleaning the Stardusts, got the materials to rebuild and re-wick them...its was awesome! That quickly faded, and even though i don't even bother anymore, I still clean, disassemble, and store the Stardust parts for future use/rebuilding.

Now I just want to enjoy the vape, and spend as little time as I have to with the actual maintenance. For me, tanks provide that.
Hope this helps a bit more.
