I love the Auzzie Gamer, he's the only LP'er I watch. I used to like guys like Game Grumps, but gradually got bored. If I wanted a 10 minute discussion that has nothing to do with the game, I'll listen to a podcast. TheAuzzieGamer puts a ton of work into his videos. He's always explaining what he's doing and why, while still staying funny. He's one of the best youtubers around, and deserves more vies.
To be fair, Game Grumps has never tried to be a let's play channel (Jon has even said more than once in his own vids and on Grumps that he doesn't like let's plays at all). It's more like a talk show (or sometimes a sitcom, lol) where a game plays in the background and the two hosts occasionally react to it. It's more about Jon and Arin than about whatever game they happen to be playing at the time.
As for my own preferences... it really depends on a lot of factors. I generally prefer more, serious, I guess let's players. People who take some pride in their content and don't just do one take and slap it up on youtube. I also prefer people who act like themselves. Far too many let's players try to put on an act, to be overly silly, or overly scared, or try to be more funny than they actually are, and it just ruins the vid for me. A let's player needs to play to his/her strengths. If you're naturally funny, roll with that and be funny in a natural, non-forced way. If you're more mellow and detail-oriented, be that. Do some research and pepper your LP with interesting facts and observations.
Also, no face-cams, please. I have no idea why so many of them do that. No offense, but if I'm looking for a let's play, I don't want to constantly see you in the corner of my screen, staring back at me absently. It detracts from the game, which is really what a let's play is all about.
Another bit of advice from someone who's seen too many bad let's plays. Learn to edit, even just a little. Yes, sometimes you do need to show off your deaths, but don't spend 5 minutes dying on the same part, or have half your video be you getting back to the point where you died last time. You don't have to be a super l33t gaming god or anything, but when you spend more time trying to get back to square one than you do making progress, then you're just wasting your viewers' time.
