I stick with variations on the same thing. I don't have anything exotic. I do suggest on your current equipment that your also eventually try the other most popular ways of using your batteries - a non-tank 510 atomizer and drip tip for testing juice samples and vaping very thick juices, and try cartomizers (the most popular way to vape thinner juices on 510 threaded devices). At minimum you will have a simple way to test new juices and the cartomizers for backup if you have tank atomizer problems. And you may prefer the cartos at least for clingy flavors that can stick around in an atomizer like cinnamons and spice flavors, ginger, etc. Boge are most popular and since they are metal they are suitable for even cinnamon which can damage some plastics.
FYI - it took me a couple of months to try to fill a blank cartomizer. I was resistant to change. You don't have to try new stuff right away.
As for personality change? I don't think so. Many early adopters were gadget freaks and some vapers do buy a lot of impressive stuff. I don't own anything like that. It's fun to buy new stuff and try it but I am pretty cheap. BTW my Toyota Corolla is now 12 years old with 200,000 miles.
BTW right now I do recommend you get a spare charging cable, and hopefully you have 2 or 3 tank atomizers, and plenty of juice.
