I know reverb should be subtle and I've learned to use it in a send condition with excellent results.
I was about to buy one (Valhallaroom) when I decided I really didn't know all the free ones we already have very well.
There is the Cakewalk set:
FX Reverb,
reverb, 
reverb mono
studioverb 2, 
Then there is the Sonitus reverb
And the free Voxengo OldskoolVerb
The free Kjaerhus Classic reverb
There is the linear one, Perfect space that is supposed to be good but gives problems with dropouts due to intensive CPU I understand.
I really liked the Valhallaroom demo a lot due to its simple helper noted settings but it's $50
Yes I could buy X2, and a new computer to make it work and get a hobbled Breverb or buy the real one for $200.
Is it just whatever turns you on in the end?
It's very hard to compare apples due to the differences in control options.
I worry I'm ignoring a quality plug due to lack of familiarization or spending wasted time on a problematic one.
 
 
 

Although I've been using Softube's TSAR-1R mostly the last year or so, I always felt that the Sonitus reverb gave me quality results and was quite happy with it.

I wouldn't even hesitate shelling out for ValhallaRoom if I were you. It has to be the best reverb for the money. I love everything about it. The quality is gorgeous, the interface is beautiful and the presets are everything you'll ever need. I like the sound of it better than Breverb. 

Thanks Sharke, nice to get reassured.
I am impressed with ValhallaRoom for sure.
The GUI is deceptively simple but I do like the sound.

And thanks Leadfoot, I'll investigate the Sonitus reverb closer.

great point about ValhallaRoom.
the gui looks rather like a homemade basement software but the sound is really nice

Thanks CB, that's 2 votes for ValhallaRoom.

That's what I like about the GUI. It's beautifully minimalist and makes a nice change from all of the skeuomorphic 3D monstrosities that try to simulate "real" controls. I don't know whether I'm just being swept along with a trend or whether my brain really does prefer the less-is-more approach to design, but my eyes were instantly attracted to the ValhallaRoom interface. 

Sorry Glenn. Didn't mean to mislead you. I was going by the title of your thread, and thought you wanted opinions on the best stock Sonar reverb for X1. I hear that Exponential Audio has an awesome reverb. I believe it's called Phoenix Verb.

X2 Pro has breverb, which is very nice.  The nicest algorithmic reverb yet included w/ Cake.
 
And Softube's Tsar is sweet sounding too - the version that came w/ the Prochannel.  With those two and Perfect Space (w/ lot's of free or otherwise impulses) pretty much cover the reverb bases.
 
While I'm working I'll use studioverb for low cpu 'verb.  It doesn't sound bad at all.  Sometimes I keep it in the final mix since if it ain't broke, don't fix it.
