Welcome!
Your challenge being in Israel on ECF is many American vendors people might suggest may or may not ship there.
I don't know if Dekang is better than joyetech. As far as I know joyetech= equipment and Dekang=
juice so by default Dekang may just be better because that is their specialty.
Juice is really subjective you love what someone hates and vice-versa.
General tips would be try out different VG/PG levels if at all possible to see what you like the most. If you can get different nicotine levels. If you where a pack or more smoker I suggest at least 2 small samples of 24mg juice.
Do not buy a 30ml bottle before trying a smaller sample! Most vendors offer 3ml, 5ml, or 6ml sample sizes.
Be careful of vendors charging 1$ per ml / 10$ for a 10ml bottle of juice. Do a search about them. Make sure they are a reputable company. 1$ per ml very expensive.
Branch out with flavors. Don't just focus on tobacco. You may find you like something besides tobacco very much like apple, grape, cinnamon, bubblegum, ect.
Good luck on the hunt!
