QT vs NS - Questions

Hello and thanks for considering my questions.

I'm a longtime user of the orginal Soulseek and am thinking of trying out QT. I'm familiar with a lot of the inherent differences when it comes to features. Though I've searched the forums, the answer to whether NS and QT can be run side-by-side eludes me.

Question 1:

Is it possible to run QT and NS at the same time? I'd like to try QT before replacing NS outright.

Question 2:

QT vs NS... which one has more users? Is it the difference significantly weighed in either direction?

Thanks and apologies for having asked questions that have likely been answered previously but ones that I've been unable to find.

UPDATE:

Thanks to anyone who considered my questions, above.

I have since found the answers; they were in the forum all along.

To anyone else who has questions regarding Qt - I'd like to point in the direction of the very helpful manual written by user "leijsten".
