I can understand - but I probably need more detailed information (and, also, specs / results to back them up):
Does it make a difference if you freeze bloatware first and leave Blah? Are you comparing Blah on stock versus no blah on stock, or blah on stock versus no blah on bloatfree, etc.
I have a ton of apps that are chewing up RAM via services, and every now and again my phone just acts stupid. I realize that it is mostly Blah's fault, but still, there are some really snazzy things about it....
I think I need o put a bloat free blah free ROM on my phone and then I can pretend I've OCd my phone
I don't have any concrete numbers to give you as I never took benchmarks before I loaded Liberty. What I can tell you is that Blur was invasive - the FB integration interfered with the FB messenger app by not allowing push notifications for new messenger. It also interfered with the contact sync.
I started off with freezing stuff like CityID, Blockbuster, VCast, basically any app that I would never use and also sat in memory. I ran LauncherPro but the blur launcher remained in memory. The Moto keyboard was slow and sometimes had touch issues. The dock service was very buggy and I often could not navigate around the phone once it launched. (home button didn't work...and if I manually exited it, I could not relaunch it unless I took the phone out of the dock and put it back in) There were also numerous random force closes in the browser and sometimes LP.
Honestly, I was disgusted with how many bugs Moto released this phone with. These weren't even little bugs - they were bugs that hampered with me using the phone. If I was an average user who simply wanted a phone that worked, I would have returned the Bionic by the second week. (I still kind of regret not returning it, after seeing Prime and the RAZR on the horizon)
When the FXZ file for the Bionic was released, I flashed Liberty, with all of the moto stuff removed along with Kejar's enhancements, I felt....well, liberated. The phone was fast, responsive, and it simply just worked.
I realize that the OEM's like to differentiate themselves by overlaying their own software on top of Android. Between Sense, TouchWiz, Blur, and numerous other overlays, they create variety that will differentiate the user experience for the average customer. As a more advanced Android user, I simply buy the device for the hardware. I have always loved Moto hardware which is why I stick with them. I lucked out with my DroidX as there was a lot of development done for the phone. The Bionic seemed like the next logical choice as it had dual core, 4G etc. However, if Moto keeps locking these bootloaders, I will have to move on to Nexus. Maybe the Google purchase will change all of this, maybe not. (I have the suspicion that VZW is behind the locked bootloaders and there seems to be a good amount of evidence to support it)
Sorry for the wall of text, just had to vent some frustration.
