I use my Triade more because I've been using DNAs for a lot longer and am just more comfortable with them. The user interface for the Yihi boards isn't as intuitive for me.
While I wouldn't go so far as to say the Yihi board is like a DNA200, they both offer a fantastic vape. The Yihi does TC very well, and Lost Vape did an excellent job loading up accurate wire types in the
Triade.
The Q is tall, the Triade is wide. The Q won't go as long between charges because it's down a battery. The Triade requires you to start taking care of that leather right out of the box if you want to keep it looking nice (and believe me, you do). Unless you have more specific criteria you're using to determine which device to purchase, you won't go wrong with either one and can just flip a coin.
