so far out of all I've tried the ce2's have been the best to use, clean , etc... also price wise they are awesome , also can be used on tanks !!
the ce2's are ok but they are just too bad to leak I like the vision clearomizers from gotvapes alot tho except they are pricey the ego tanks i guess would be a close second. I tried the carto tank from madvapes too but I just don't like the filler inside the carto it is like sucking a wet sponge lol
