I know how they both work, but I'm not completely sure what the "filler taste" is. I have no problem slotting cartos (though i haven't done it), nor taking primer puffs because I'm just starting to upgrade from really cheap stuff.
I used cartos exclusively for a while and only started dripping recently. I slightly prefer it so far, but I'm also using really cheap no-name 901 cartos (also upgrading battery, and well, everything else). Dripping into my really cheap no-name 901 attys seem to work better so far, but that could have a good bit to do with just using older cartos for a few fills worth…I'm too lazy to clean them and didn't try dripping until they'd all been through a cycle or two……down to my last carto now and dripping almost exclusively.
If I went with the tank, I'd probably be ordering Boges and starting with a smoktech tank. The vivi nova would be a little more expensive, but not terribly so…and it's a lot cheaper than "good" tanks (cartomator, johnboy, etc.).
I know I'll eventually try both…just kinda wondering if the wick/nova thing is a bit closer to dripping…the design seems a bit closer……but, then, I've never taken apart a cartomizer……so I don't actually know how the juice gets from the polyfil to the heating element.
