It really is the standard IMHO. I just got an RX200 and use Ti1. I used my VT200 as my reference and dialed up a TCR until the RX performed like the DNA200 at the temp I like. I sure trust Evolv more than the others.
I absolutely love my RX200 but I just went through two different tanks about an hour ago that the RX200 refused to lock in as SS but the Efusion locked them both in as SS with no problems at all. With either of those tanks I have to use a drastic TCR to keep them in TC on the RX, go figure. Once locked in the vape is still smoother & better on the dna 200 so in other words I am sold.
