Have only seen snippets so I couldnt direct you to "the best" ones.
- Filming style mostly the same, behind one way mirrors and mounted cameras.
- House is often two story.
- Not sure if this is every series, but ones I have seen have pool tables and other games, which I think defeats the purpose somewhat.
- Virtually all talk is about strategy, alliances, its rare to see HM's sitting around talking about their lives or funny stories.
- HM's in the diary room are often inter cut through the episode, much like the style of Survivor, Masterchef, etc.
- You NEVER hear "This is Big Brother", the producer doing the voiceover will often just speak or in some cases refer to themselves by name, so theres no real concept of BB being a single entity.
- HMs i've seen that get ejected dont get that talk in the diary room about what they did wrong, they just get the boot.
Even if you are ok with gameplay and strategy, in some ways its similar, but in many, it feels really alien.
