It should come as no surprise that the best reverb for orchestral music would be a convolution type using IRs from real concert halls. After all, that's THE sound that was established long before artificial reverb was even invented.
 
What's not mentioned is that perhaps the worst reverb for orchestral music is the one used most often: the algorithmic reverb that's built into Kontakt.
 
 

Bit, I know you weren't really thinking of all this in your post. When my wife and I go fishing we have a rule about making fishing decisions that respect what it took to get there. What I mean is; don't just grab a rod and start using what was tied on there the last time we went out. We save money and make plans. We buy what we need and make reservations. A certain amount of time, effort and money is spent before we even leave. We may drive up to 5 hours and then unpack the truck and put the boat in the water. We didn't drive 270 miles and do all the other things to then get lazy when we finally get to do what we wanted. Certain fish in certain places require certain bait presented a certain way. Finish it off right. All your effort and expense to get a GOOD track and you slap on a reverb because it was right there? Respect your time and expense and the learning and frustration and expense. And the time and expense. And all the time and expense.  We all have way too many really good plugins, that cost a good amount of money. Don't let down on the last step. Choose the correct one for the particular purpose. Run through the tape at the end of the race. 
   So, BD are you saying, "don't be lazy and put a spring reverb on a French horn?" Yes. Yes, I am.

Without reading the linked story, I'd think the best reverb would be the hall sound recorded with the strings.  IOW, there ought to be several mic positions you can control from within the string library.
 
Unless the strings are recorded completely dry, any 3rd party reverb (alg or convo) would only be added on top of the natural reverb of the recorded strings.

What?!? No love for EW Spaces?

What?!? No love for EW Spaces?

That's what I would be most likely to use, I like it a lot.

Ewe, spaces...

BTW, EW Spaces is part of their Memorial day sale. It is 50% off. I had recently bought Meldas and Waves IR convolution and could not justify another convolution, but wanted it. 

Quite interesting that VRoom is mentioned but VVintageVerb is not, though it includes some of those Lexicon style algorithms. My personal favorites for orchestral are FabFilter Pro-R and EastWest Spaces.

I have QL Spaces which I use quite a lot.
 
VSL Convolution and Hybrid reverb which are part of the VSL Suite are good yet limited in patches. You can however load your own presets from other impulse responses and make your own patches (if you are that way inclined).
 
I'm not a fan of wet reverb in orchestral samples as it limits how you can use them without them sounding the same or out of place when used with other sample libraries.
