As for the best kind of wire, do you mean Brand? Or type?
If you mean type... I find Ni200 Extremely annoying. Everything I build ends up being like 0.02 ohms... I read that in order to get my coil at 0.5 ohms, Ill need about 75 wraps on dual coil... which means I should be good with 35 on single coil. Yay.
now, 316 lvm stainless steel is good in my opinion, if you want temp control... but if not, there is not a whole lot of point
Clapton
coils and twisted
coils are easy to get and cheap now, Ive been running a dual clapton for a while and I enjoy it.
Havent tried ribbon, Might at some point. We'll see
If you just mean different brands... They are all the same in my opinion... Not enough of a difference to warrant any thought.
just my opinions.
