The Realme 6 has a plastic back but the Pro has a glass one. A dude online tried to scratch the Pro with keys, a coin & the point of a boxcutter & it didn't leave a mark. He pooled water on it, sprayed it with a plant-sprayer, wet it completely with a hose & finally dropped it into a bowl of water for 10 seconds or so & it was still perfect. He tried to bend it with his hands but it stayed perfect. I bought one a few weeks ago & I love it. My wife has a 6 & it's an excellent phone too. The 6 surprisingly scores a bit higher than the Pro on AnTuTu & GeekBench but the Pro scores higher on GFXbench. Both are great value for money.
