For me the 901 atty vapor is warmer than the 801 atty and for me the 901 atty taste better than the 801 atty. for me the vapor is very good on the 901. I understand that taste throat hit and what is a good amount of vapor is different from one person to the next but that's just me.

Most pen style batteries do not deliver 3.7 volts which determine how hot the atomizer gets. The stick does. Consistently. If you require the same 'heat' to the vapor as you get on a 901 on a SD you will be disappointed. This is not to say the "thickness" of the vapor is not there because it is and then some.
