Default NGK Spark Plug question

So I'm due for changing my spark plugs and I'm looking around trying to figure out which spark plugs I should get and I've seen some different NGK numbers and I can't figure out the difference between them.

I was looking at the NGK 5306's and the NGK 4306's.

I saw a post by chefred saying that the 4306's are for more heavily modded vehicles but I cant tell why when looking at them. The 4306's are cheaper too so I'm just trying to figure out which ones I should go with.
Supercharged, cammed, other things too!
