I think we all agree that we should recommend what the OP wants/thinks might work for him/her.
But there's one more variable, which I always consider when making recommendations to new vapers, and that's tobacco harm reduction. I believe that recommending the smallest and safest tool that will do the job is never a bad idea. We don't know yet what happens when we vape at
very high temperatures and inhale huge amounts of vapor into our lungs 24/7. Dr. Farsalinos is looking into it as we speak and I eagerly await the results of this study.
E-cigarette research: temperature of evaporation
And while I wait, I don't think it's a good idea to tell new vapers that they need to start at 50 watts in order to be able to stop smoking. It may be true for some people, but it's certainly not true for all. Millions of us, tight-draw-low-wattage-tootle-puffers

, have successfully quit smoking and have no desire to breathe fire or lung inhale huge amounts of vapor.
So, based on my experience, I always recommend a cautious approach--start low and see what happens. I also don't recommend Aspire BVC coils because I'm not convinced that using fiberglass wicks is a good idea. I don't recommend e-liquids containing diacetyl because it's an unnecessary and completely avoidable risk.
One can always get a more powerful device or a diacetyl-loaded custard juice if that's what it takes.

We have choices.
