yup if it's 3.7 volt they should perform the same. The only variable which i found can make a difference ir airflow through a
mod..that makes a difference with vapour production.
Apart from that the only other things are form factor and what you personally like the look of, and ofcourse what
batteries they run from. a 10440 will perform the same as a 16340 it just won't have as long a runtime.
I'm seriously looking at a regulated 5volt mod soon..just to see what the difference really is ...
