I really prefer raw material over edited.
https://www.youtube.com/user/LordMinion777 LordMinion777 keeps his footage mostly raw, he based his channel off that completely, he got his big boost from being friends with Markiplier but has done well to maintain the channel on his own. I can't stomach un-edited content too much, especially if the commentator isn't that entertaining or has a lot of quiet moments, so I only watch his channel on occasion but I do still enjoy watching his group/multiplayer LPs. As for reactions, sometimes I can't tell if he's being genuine or not although he did make a vlog explaining that he does try to express his reactions more instead of keeping them to himself which is understandable when it comes to gaming and being immersed, I had the exact same problem when I started out and still do today.
https://www.youtube.com/user/TheSw1tcher Two Best Friends Play / TheSw1tcher is another channel reknowned for full blown group let's plays that are kept raw, only raw channel I can stomach the most really, although Matt has started a No More Heroes solo LP, surprisingly he does really well solo too. These guys have special series' as well like Friday Night Fisticuffs which is bascially them playing a single fighting game for like 1hr or something, they do Shitstorm specials for halloween and just play as many horror type games as they can within an allotted period usually 30days or so. The only time they edit is when they have vids on Machinima Respawn (part of their contract) they do sometimes do sports games but primarily wrestling games, nothing like Fifa though. Their vids can range anywhere between 20mins to 1hr long, usually the one off vids are 1hour long. Sometimes they do LPs with 2 people, sometimes they do it with all 4 or sometimes 3, very, very rarely 1. They even have random skits and some vlog style vids every now and then, also do 3hr podcasts lol In fact they were the first channel I subbed to and an inspiration for my couch LPs.
https://www.youtube.com/user/TheRPGMinx TheRPGMinx sometimes keeps her footage raw too but does cut out the boring bits here and there, her reactions actually still seem genuine, the benefit with her is that she really doesn't care what a lot of people think so she does her own thing without forcefully trying to impress too much, at least from what I can see.
https://www.youtube.com/user/AlloySevenVideo AlloySeven is a good small channel, he's the guy you'll probably recognise mostly for his copyright tutorials on YouTube but he does tutorials, does vlogs, LPs, reviews and stuff like that. He started a recent series called "Gamer Life" which is a vlog series. He used to be on these forums but he said something happened and he couldn't log on anymore for some reason, kind of sad the community would benefit from his info.
https://www.youtube.com/user/xXBlubearXx BlueBear is another 1, actually a user on this forum, she edits but her content does come off raw-ish so you're getting the whole works too, there's boring bits obviously cut out. She does how tos for WoW and even started a recent leveling LP for WoW. Does other LPs as well.[DOUBLEPOST=1422961353,1422961191][/DOUBLEPOST]Omg how could I forget Cryaotic not subbed to him but he has an awesome voice and does raw LPs from what I know.
