Its hard to compare watts when it comes to the CE2 .... they are whole different animal and don't cross over well when you got watt for watt.
That said, I think when you have a CE2 working well it has the absolute best taste of any atty/carto out there.
I used them full time for 6 months before I got a REO.
The problem is getting (or keeping one) working well.
I'm pretty confident the biggest cause for lack of flavor while learning a REO is the atty being too wet.
Blow it out .... drip a few drops and fire ..... If that hit has good flavor your in the ball park and just need to adjust your squonking.
