I personally think Matt & Rylan compliment each other really well. Yes, Rylan can be a little OTT and off at times, but Matt brings it back around to the point or question in hand and he isn't afraid to go against the grain, even with Simon.
Matt's my favourite, I enjoy his dry sense of humour and straight to the point approach. Rylan's good at what he does too by bringing a lightheartedness and fun approach to the show.
Good duo.
