I'm not trying to take nothing away from the Evo but, this my opinion how the phones stack against each other.
In the way of quality, I would say neck and neck. The DX is although a solid piece of hardware not to mention newer. 4G is not accessible everywhere and some of the people I talked to whom own an Evo, don't even get 4G 1/3 of the time; o-wait, let's not forget you have to pay a $10 4G fee. The hardware is older then the DX on the Evo, and no, not by much, but enough to cause a difference of negative FPS in benchmarks when the processors are kept at stock speeds. Why would slower technology be better then newer and faster technology? Oh wait...because it has a kickstand
please. If I want to watch a movie, I will do it on a proper TV. Droid X has the gorilla glass LCD display, never a scratch on my screen and I went months before picking up an Otter Box Defender. I have noticed on the Evo, when looking at through the bottom of the screen, I can see several back lights illuminating the screen, exactly like the Droid 1, but not on the Droid X. Motorolla didn’t miss this. The Evo has a lot more development in the way of ROMs, themes, etc...but the DX has some as well. Doesn't matter, 98% of people with and Evo or Droid X have no idea what a theme or custom icon APK file is let alone a custom ROM. HDMI out? While I am more likely not going to use it, I would use my HDMI out before I used a kickstand lol. Three microphones on the DX, recorded video's audio sounds amazing when played back. Motorolla really left no stone unturned when it comes to quality with the DX. Sure it has a locked bootloader, but that’s another topic and one that really has no relevance. The DX is thinner and more attractive phone in my opinion as well. The lines and candy bar like styling is what gets me.
It just depends on what you plan on using your phone for. Both phones offer unique features but I for me and anyone I would recommend a phone to, a Droid X has the edge over an Evo.
Sadly, technology becomes a thing of the past every six months, the Atrix is where it's at in the way of super smart phones, soon to be followed by all the other Dual Core phones. The Droid X or Evo is more then enough phone for today’s mobile phone needs, it’s just up to you if you need the latest and greatest.
Droid X for the win
