Hi Saeybia and welcome.
I'm pretty much a newb too, bought my first real vape last xmas. I've tried coils ranging from 1.0 ohms to 0.20 and I've yet to see a recognizable difference in their output as far as the vape quality is concerned though I have noticed some juices seem to vape better with lower resistance coils than others. What I've read suggests that with higher resistance the vape is supposed to be cooler,smoother, and more tasty. Lower resistance is supposed to have more of a throat hit and larger clouds. I'm not yet convinced by my own experience of the truth to that.
I'm using 0.5 ohm coils in a number of my atty's and they seem to perform well. Of course when you change your coil for a different resistance one you will normally have to change your power setting to compensate. The higher the resistance the lower the wattage and vice versa. I started using the power settings (wattage) because I couldn't understand the Chinglish instructions that came with my Evic nor could I identify what the coil wires were made of in order to select the correct temp control program. I've since figured that all out but still find myself simply using the wattage setting as it is a simple and understandable method of controlling the amount of power. Do try the higher resistance coil though, in fact if you can get others try them too. This vaping thing is all about experimentation to find what you like and of course you'll learn more each time you do experiment.
What I've found that works for me and was recommended by someone here with more experience is that when you start with a new coil, prime it well and give it time for the juice to start wicking well before trying to vape it, maybe 15 to 30 minutes. Start by vaping with no power and with the airflow closed down, that literally sucks juice into the wick. Then open your airflow and start taking draws at a really low power setting, maybe 5 watts and don't expect much. Work your way up a few watts at a time and what you should notice is that the vape starts with nothing more than a bit of taste, then you'll start getting small clouds and the coil will start making gurgling and popping noises sounding very wet. Higher still the wetness starts to diminish while the taste increases a lot, often too much, but it is still a wet vape and may be spitting hot juice. Higher still you should pass a sweet spot where the wetness is pretty much gone, the taste has lightened, and the clouds are substantial. Higher still and the vape starts to dry and become warm, and the taste starts to disappear. Then start lowering your power to find that sweet spot again. It changes with the resistance, the specific juice, and even how you are feeling that moment.
Just as a very rough guideline I end up in the 10 to 18 watt range with a 1.0 ohm coil, 30 to 50 watt range with 0.5 ohms, and 40 to 65 watts on a 0.2 ohm coil. But again it depends on a few other factors that I haven't mentioned. Play, play with power settings, with different coils, with airflow settings, with different juices, with different juice mixes, and look forward to being able to play with different devices.
So have fun and keep experimenting, reading, and asking questions along the way. Best part is that we've all got lots more to learn. (sorry for the excessive verbiage this morning)
