I may have some bad news for you, but I'm gonna give it to you straight. Cig-a-likes will not give the same performance as a larger
device.
I don't carry around something that looks like a garage door opener in my pants because I like the size, it's because I like the superior performance.
In order to get a warmer, more satisfying vape, you may just have to upgrade your gear. If you will be upgrading from cig-a-likes, then it's safe to say you will absolutely have to bite the bullet and get something that looks nothing like a cig. I was very hesitant to get a larger device. I wanted to keep as close to the size and shape of a cig as possible.
I spent a lot of time and money, gradually upgrading devices (and consequently increasing the size) until I finally decided "@#$% it, I'm getting a big honking box mod just to see where this goes from here." Should have done it right off the bat.
Not saying you have to get a box mod to get an incredible vape, but you will have to come to terms sooner or later that the best experience can only be had by a device that is built for performance, not to resemble a cigarette.
