What should I get next after Caliburn Explorer?

Heya, so I've had a Uwell Caliburn Explorer for a bit now and I'm thinking of getting something new/better. I've been browsing some e-shops looking at different brands and such but I came to the conclusion that I have no clue what exactly to look for. I would want preferably something that gives more flavour and doesn't burn the coils as quick while smoking 20mg nic-salts. I would be really thankful for any advice as on what should I be looking at. Thank you
