Always a tough choice between these two...
I'd say Guri with SJ just because you'll likely run into some TLTs.
I like LW on Guri personally when I use SJ, but not sure what you'd do with that extra point anyway. Inertials I guess, but Predator is good too.
I think its a solid list regardless of which Star Viper pilot you go with.
Personally, I really like Advanced Sensors + Push the Limit on Xizor instead of the VI + FCS. Throw in autothrusters (and the required title) and its 40 points. Its more difficult to use than a Guri however (imho) because you absolutely have to plan 2 moves ahead every turn to get the most out of advanced sensors Xizor.
When going with Guri, I prefer predator here, simply because with 3 other ships, its harder to keep Lone Wolf active (I really like LW + SJ on Guri, but only in 3 ship builds).
Having said all that, I think the biggest weakness for the list is arc-dodgers, and the VI + FCS Xizor (with flechette torpedoes) is probably the best build to deal specifically with those. So that might be the best choice...even if its not my favourite 
That Guri load-out is my jam...
My new take on arc-dodgers is that even at PS 9, you do not have an init bid (and if you did they could have one too) and you may not have the choice of initiative to dodge arcs... The same would hold true if you were PS 10. In that scenario, Guri is going to function the same against aces but with a lot more success.
Personally, Guri's ability + Predator is awesome in the 'stress meta'...and if you are not stressed, it allows you to boost and barrel roll into position to block aces or take advantage of lower PS foes. She cannot do it alone against aces...she needs the Marauders backing her up with potential blocks and arc coverage.

Its not the PS9 that makes the difference, its the flechette torpedoes.

I wonder if Wired would work out better than VI on Xizor.
If you don't take VI on Xizor, then Guri is the better choice IMO.

I ran something like this in a tournament recently (3 Marauders + Guri), but my Guri had Outmaneuver and Advanced sensors. It was incredibly fun flying her VERY unpredictably (she just about solo'd a 4Y TLT squad). However, this one you proposed is significantly tougher than my one against TLT in particular.
Xizor is certainly more reliable 
wouldn't bank on dampeners being at all useful, though. If I want to move 0, I just bump him into the nearest cannon fodder 
Both your builds are solid. I absolutely adore that guri for all the reasons mentioned. One of my favorite ships ever.
As blade says the PtL adv sensor build is more difficult to use, MUCH more difficult actually but the ship will cause problems even to higher PS dodgers simply by virtue of its unpredictability and huge threat radius. Either one is largely immune to blocking.
If you go with prince, drop dampeners on Xisor for the 1 point bid.
Guri is stronger against all but aces. Xisor can at least survive ace attacks.
Depends on meta. If meta is balanced, play whichever you find more fun.

I've probably had more games where Autothrusters were dead weight than I have had with Inertial Dampeners.
Edited by WWHSDBoth are hard targets for the opponent to choose first...so as long as you can maximize offense on each one, you should be squared away. Flechette Torpedo is a nice touch.
