Yes, Lower Resistance = warmer vape.
As a quick point of reference think of it kind of like this.
On an eGo type battery (from 3.2v to 3.7v [Average under load tends to be around 3.4v] over it's charge cycle):
1.5 Ohm LR - Simulates
vaping a standard 510 atty at 6v.
1.7 Ohm LR - Simulates
vaping a standard 510 atty at 5v.
2.0 Ohm LR - Simulates vaping a standard 510 atty at 4.2v
2.5 Ohm 510 Standard/Regular range - This is the standard 510 range...it's what comes with regular mini 510 type batteries and performs about like a 4.2v (KR808/901) battery with its native 3 Ohm stuff.
3.0 Ohm - This is standard for 4.2v devices like KR808D-1, Riva SE, 901, PigCig, iGo, etc...performs similar to a 510 kit with it's native 2.4 Ohm stuff.
3.5 Ohm and above - HV stuff...made for 5v and up devices.
Note this chart is not 'exact'...as no two stock batteries/atties are going to be exactly like they are rated (with exception to some of the higher priced regulated ones). There is a small tolerance level in there (just changing juices can change the resistance of a carto by .2 ohms)...but this kinda gets you in the ballpark.
Note that the CE2 gives you more choices in that 2.5 to 3.0 range. The coil is also closer to your mouth...so in theory a 2.4 Ohm CE2 might feel more in the ballpark as a 2.0 Ohm bottom coiled carto, and even that is somewhat subjective to individual preferences.
