I will be the first to admit that I have a problem.  I go through phones like nobody I know.  I've made some posts on the line of "vs" before.  And I must say that I've got some really good response.  So... Here goes another one.
 
Prelude... I came from a Blackberry, to the Iphone (AT&T - SUCKS!), back to a Blackberry (after having the Iphone, the Blackberry just doesn't do enough cool stuff), then to the Moto Droid, then to the Eris, then back to the Droid, then to the Incredible, now to the Droid X.
 
Yes, I know... I'm nuts!  
 
 
Physical Comparo....
The Droid X is HUGE!  I just had to get that out of the way.  Oh, and yes... It's HUGE!  Enough said.  While the phone is large, the weight of the phone feels VERY similar to the Dinc.  In this user's opinion the X seems a little more SOLID (if you will), than the Dinc.  I think it's due to the Metal Housing and the non-slip coating on the phone.  The Dinc feels very plastic compared to the X, however with my silicone case on both, they feel equally solid.  Once you start poking around on the X the inc feels very small.  I like the physical buttons on the X, but the X doesn't have the optical tracking point.  I find this to be a small issue, but I like the option and find that I use it quite often (the optical wheel).  Do the physical buttons make up for it... probably, I'd probably call it a wash.  There is a bulge at one end of the phone... the camera end.   I actually like the bulge and think that it makes the phone more comfortable.  Also provides a little bit of a perspective bonus when sitting on the desk.  Has a little built-in tilt on it.  NICE!  Both are easy to fit into any pocket and shouldn't really be an issue as far as comfort goes.
 
Screen.....
The X is obviously a larger screen and is much easier to live with when on the internet or doing other media related tasks - size wise.  The Dinc's screen is actually nicer in that its got a richer more deep screen.  Hard to articulate, but the Dinc is a warmer more pleasing screen.  The colors seem to be sharper, the blacks are blacker 

 and the contrast is just plain SWEET!.  The X seems to be a little washed out compared to the Dinc.  The colors are still nice, but again, not quite as EYE POPPING.
 
Sound.... 
The X just plain beats the call quality of the Dinc.  Sounds better on both ends in my personal opinion.  Easy test to do... just call the other phone and keep switching back and forth.  My wife agrees but likes her new-to-her Dinc  

.  As far as the MP3 playback and sound.  I haven't got a chance to load anything up in the music department, but the Dinc seems to be on the quite side of things compared to the Moto Droid.  I'm going to assume that the same holds true for the X.  The ringer and notification sounds seemed to be on the quiet side for the X.  Not sure if this is normal or just me losing my hearing.
 
Sense UI vs. Blur UI...
I like the Sense UI better.  It works, is better to use and to look at.  The X is now using Blur.  Better than straight Android, but still lags behind SENSE.  Somethings are very good on the X.  The contact scheme and interface is actually better than that of the Dinc.  The screen scrolling has some cool features and probably are a little more friendly that that of the SENSE on the Dinc.  But, at the end of the day, the Sense UI wins out.  I may change my mind after a couple of weeks, but for now, the Dinc has it.
 
Stock Apps....
This is a toss up.  I will say that because the X comes with Swype and my Dinc was running a beta version, the X wins the Swype war.  Problem here is that with such a big screen, you are really working the fingers.  Yes, you can be more accurate, but make sure you stretch before attempting any such activity 

  But back to apps, the X has Blockbuster... big Whoop!  Lets just call it a toss-up with a side note:  Stock Swype.
 
Battery....
I have the 1750 in the Dinc, so I already have more battery than stock.  The X has more battery... done.  But not by much compared to the 1750 in the Dinc.  Then again, I've only went through 1 charge cycle.  I'll be better prepared to compare the battery in another week or so.  So far though... so good... or should I say Better.  
 
 
Processor Speed....  I think it's about the same.  I've tested it side by side and I go back and forth.  Getting on to the internet is odd.  Out of ten tests they'll split the wins.  So, considering I'm not a processor geek and testing the processors on some sort of scale... It's a toss-up.  Real world though, you would have a very difficult time picking a winner.  Both VERY fast.
 
Camera.... The X kicks the Dinc's but.  The camera takes some pretty incredible pics (sorry about the play on words). The video on both is pretty good, but with the X I can go straight to the TV and play what ever is on the phone through the HDMI out - COOL!!!!!    I loaded Avatar up on the phone and played it in my theater last night.  No glitching, no pausing... Very cool.  Really like having a portable DVD/Digital player.  Very cool.  did I say it was cool????  
 
 
At the end of the day, and when the fat lady sings.... I cant give the X the edge.  Both seem to be very solid.  Both do the same things in very similar ways.  The big screen is nice, but the Dinc has better color.  The cameras are great, but the X is better.  They both sound good, but the X sounds better.  See where I'm going????  Both great phones and both are winners.  You choose!  For now, I'm carrying the X.  We'll see what happens over the next couple of weeks.
