In terms of priests or influencers you should stick to one denomination. It is not a good idea to listen to different priests or preachers from across the christian religions. This might be confusing, since you might get a lot of different interpretations of the scriptures.
Also you should stick to the one "near to you" i.e. if you're in USA, "Saint Herman of Alaska Orthodox Church, Stafford Va" might be one for you.
Father Spyridon is a good fit for people from the British Island I think.
Vater Abt Paisios is a good one for germans.
