How do you rank encrusting corals like psammacora, leptoseris, leptastrea and cyphastrea from least to most aggressive?

Anyone have any advice for placing encrusting coral on the sides of vertical rock structures where I want to place acropora, digitata, stylophora and seriatapora at the middle and top of the rockscape? Which ones would you recommend or avoid based on your experience? When and if they meet, who would be least likely to overgrow or kill the acropora?

Avoid Pavona. Had to rip apart my reef last year to remove it from one of my structures. Still need to deal with it on the other side of the tank sooner or later.

Thanks, that's one I hadn't considered. That's the type of situation I'm hoping to avoid.
