When it comes to noise floor, my physicist brother determined I didn't have any Mics that could test it because all my Mics had a higher floor. I don't know what RME uses to test levels so low but not cheapo Neumanns.

 
They would not use mics for noise floor testing but rather signal generators.  But, yes, even high end measurement microphones will have a self noise higher than the recording device.  
 
I haven't used a MOTU since the 828mkii.  While I liked the interface and software, the sound quality and build quality were not on par with RME.  I am using the original UFX along with an XTC preamp for my remote recordings.  
I use a Babyface Pro in my studio for editing and post, and I am thinking of getting a new UFX+ for my remotes.   
 
It is not the end-all of sound quality, especially if you like a bit of color and character.  But it comes pretty close to ideal for a clean, dynamic, and transparent sound.  You would have to spend a whole lot more for better performance and would have the sacrifice the RME's stability and reliability.  Not worth it for me.

Make sure to checkout the MOTU AVB series.
The Ultralite AVB is an excellent audio interface.

I saw some gearslutz forums mention about issues with AVB driver on Windows. I got a bit skeptical about the AVB after reading this.

There's no blanket problem with the AVB drivers under Windows.  
Who's the source of this "enlightenment"?
If you try to run it on a 3rd-party USB-3 controller, you may run into issues.
If you run it on an Intel USB-2 or USB-3 controller (with a well configured DAW), the AVB series is excellent.

not the source, not on gearslutz, either
but talking to MOTU support on occasional issues where the AVB drivers just dont show up in Sonar as ASIO drivers.
they are currently suspecting something OS specific, but what can that be given that it connects fine at least 9 out of 10 times and when connected runs brilliantly stable?? that'll be the needle in the haystack ...

Are we talking the release driver... or the public beta?

I just scored a Lynx L22 for $130. I think no one mentions lynx because it's so ridiculously expensive.  There is a pci-e model called the e22.  It's specs look frighteningly good.

Lynx makes excellent audio interfaces.
I used an AES-16e-50 (AES-50 port) for a while... connected to an X32.
Rock solid performance with DAW software... and you can take the ASIO buffer size down to 32-samples.
 
If you plan to use an older PCI Lynx card, they don't work well in bridged PCI slots.
Any current generation motherboard with PCI slots is using a bridge chip.
 

I currently have the older Focusrite Scarlett 2i4. What do you guys suggest if I'm looking for something with better latency and better overall quality... But I don't need any more features. I do everything within Sonar. I don't touch anything on the interface itself or in its software that it comes with. Just the volume knob on the box, and that's it. So most of these big huge interfaces with screens and knobs and 20 inputs and outputs... I wouldn't even touch any of it. I just have an In for my Guitar, an In for my Mic, and 2 outs for my two monitors, and a pair of headphones.
 
As of now I'm probably just gonna go to the new 2nd gen Scarlett 2i4 to get the lower latency, but maybe if there's something that's truly better, but not like $2000 with tons of features I don't need, I'd consider it...

somewhere, deep in this thread,
i gave a somewhat subjective review of a product...
 
but i'm starting to think my posts are invisible......
 
there are ways to drive down to 'the biggest bang for the buck',
but then again sometimes, things just fall into place on their own.

shush now there
