Should I put a downtube guard on my aluminium enduro bike?

I am about to purchase a new Whyte G170s mountain bike. It does not come with a downtube protector to protect from rock strikes. Although the frame is not carbon I am wondering whether I should buy a guard or not. My last bike (a Trek Fuel) was also AL and came with a downtube guard included.

So should I get one or should my frame be OK with rock strikes?
