Welcome!
See my avatar? That's a carto tank sitting on top of an eVic VT. That's how much I thought of the temp control feature. Variable power (VW) works well for me. Just turn the power (watts) up or down to make your vape cooler or warmer.
I like cool vapor myself, so I'm vaping that exact tank now at 5.8W. Somewhere around 8W, the vapor gets pretty warm. It's not as tight of a draw as a cigarette, but it feels very close.
I don't use cartos in them, though. I use atomizers that look like cartomizers. I can't give you a link right now, though, because Madvapes is one of the merchants that went offline today out of protest.
But if you're interested, they're by Smoktech, and they call them "DCT Atomizers".
I get where you're coming from on the loose/tight draw thing. Remember that high powered, low resistance devices are really made for big, airy draws. They can get quite hot and dry otherwise.
I don't know what the best beginner setup is, but I'm having a nice vape right now.
