I rather fancy Moses, although I think he could benefit from doing videos with more in depth conversations or meeting people to do interviews.  That's just my opinion, because the level up videos get repetitive with the same kinds of conversations being had most of the time. 

Steve is cool too and I think he could do the opposite and get out and to meet new friends more often.  

They are probably two of my favorites as they never hardly brag or make videos where they try to show off how many languages they speak (like alot of other youtube polyglots).  Plus they also help people learn languages as well.  Also I like how they both learn a variety of languages, not just a bunch from one area, or only romance languages as is the common practice.

I agree with what you said about Moses and Steve. It is usually the case that one person needs to get more social and the other person needs to get more in-depth woth the languages. Wouter, the guy from the Netherlands, needs to get more in-depth too. I enjoy añl the videos and respect all their hard work.
