That's very true, not enough bands try to get a unique tone anymore. It's always Recto's or Marshall's, or maybe a EVH or Peavey 5150/6505 for metal bands anyways. Like for instance, not too many bands are rocking the Mark series, which are very unique sounding. This is partly because if you're in a band Mesa would rather you be playing their popular models because it better helps with their sales, and also, everyone has heard of a rectifier, not everyone has heard of a Mark series. So they go with the tried and true and don't give the alternative a try.
I'm not saying you can't get a unique tone with a recto either... CC do cause they're boosting them with metal zones which really saturates them, But it's harder to stand out from the pack if you're using the same gear.
