They cost so little it does not hurt to buy both and try it.I personally don't think you will notice any difference.A lot of this is personal preference,not much is based on science.You cannot keep trying to get the best based on random polling,only a general idea of which way to go.Base your purchases on what you can afford and work with what you got and quit second guessing.I use Joye 302,510 and DSE 901 attomizers and I get good vapor from all at 3.7 volts .The only reason I have three different atty's is there was a dry spell where you simply could not but a 302 atty for about three months last year.
