I've been using Tatsu, Solaroam SH Upgrade, and Shooter side by side for close to a year now and I have them in this order...
#1 Toray
#2 Shooter
#3 Tatsu
All are amazing lines and I'd be just fine if I had to use any one of them exclusively. However, I'd prefer Toray (BC only, FC's and spinning gear aren't my thing) over any other. A Uni or snell knot is insanely strong with it. The abrasion resistance is the best I've ever seen. Low stretch. It's all I can ask for in a FC line. Shooter is alright. The biggest problem I have with it is that I can't find a standout "best" knot with it. No matter what knot I tie with it, every five or six knots I tie PAP! one will break with not a ton of pressure. I had a hell of a time breaking off a hung up jig the other day but, still have that occasional weak knot. If I were to use one on spinning gear it would be Tatsu. I think it handles the best of the three but, along with the good handling comes a little more stretch and a slightly weaker line.
You may have a completely different outlook on them as I do. I kept buying different FC's because so and so said it was the best with no stretch, etc, etc. Then, I would try that line and find that it has more stretch than silly putty. So, I bought all of them. Fished all of them. Now, I know which one to buy.
