I appreciate how "hands on" Bam is this season. It's true that Bam lacks the showmanship that Sam has, but what he's lacking at showmanship he makes it up by being fair with all the fish. If Sam hosted season 5 again, he would just written off Vicky for just another whore who can't shut the fuck up and would make her burned out day 1. Bam instead gave her a nice support, keeping her for another day of crash out or even giving her a change to win (I know, unlikely.) I think Bam being an ex-piece of shit himself, helps him to tolerate these people better.
You can kinda fell that Sam is very judgmental at times and even see some of the contestant to be beneath him. The prime example of this is in S2. Sam really tried to mold TJ to be a "better man" by telling him to cut his hair, wear shoes, and work out. Another example is when he gave Greg advice on how he should stop making "kiddie shit" videos without telling him outright what kind of video he should make.
