Full freq. range reverb like this?

Or just keeping the 200Hz - 5000Hz freq. of reverb and filtering all the rest like this?

I think the filtered one sounds closer but the full range one sounds similar as the Maxwell's one.

Reverbs are usually filtered, because real reverb (the kind that happens acoustically in a physical space) does the same thing. That's why full-range reverb sounds unnatural.

I mostly write very sonically "dense" music so the little bit of verb I do use I try to keep away from the lower frequencies to avoid "muddiness/cloudiness". I just like it on top to give a bit of a "room/open air" effect whilst keeping the bottom end as tight and clean as possible.
 
However the less dense the mix the more verb you can add (and lower down).
 
I watched an oooold video about mixing theory (and Bitflipper... I'm sure you know the one I'm talking about) that used a 3d graphic virtual room to show where and how the auditory system perceives certain sounds, freqs and volume levels.
 
The point they made on reverb was that you want to use it when your auditorily perceived "room" is "empty" and needs to be filled up a bit (if the material benefits from it). They showed this within the 3d graphics by little tiny blobs being scattered throughout the virtual room... and those blobs of course being driven and scattered by much larger blobs representing the main instrument(s)/sound(s).
 
So I kind of look at it this way (after playing around with that concept on my own stuff)...
 
If a part of your room is already jampacked (meaning frequency bands and/or stereo positions) then you likely don't want to crud it up with a bunch of reverb. Areas of that room that are less cluttered but maybe sounding weak/thin MAY benefit from some carefully applied verb.
 
Honestly I find reverb/delay effects to be the most complex and finicky concepts/tools to apply. Even more so than compression in many cases.
 
But that idea of only jamming it into the "open" space of our 3d room (when necessary and SPARINGLY) has helped me quite a bit.
 
Sorry I did not check your links and I'm not a pro engineer but thought that might help.
 
Cheers.

Just from listening, I think I preferred the latter (filtered) reverb ... it has a more intimate authentic feel to it, where as the first sounded more smooth and glossy. Then again both versions sounds good, and I'm not sure I would actually be able to pass a blind test in this matter :) Maybe I'm biased due to past problems with mud in the lower register of the mix as a consequence of not properly filtered reverberation.
