The most significant fact is that Gai with Night Guy can bend space(Space-time actually, since space and time is connected and there is something called Space-time ninjutsu) while Sasuke can't. Though, their speed can't exactly be measured, someone that can distort space with their movements logically should be able to move a lot faster than someone who doesn't.

Sasuke's Amenotejikara has been shown to vary in speed, if he shifts positions with an empty space it's shown to be slower than when he shits positions with objects, also it has a limited range and cool down. Just because Sasuke can see Guy doesn't mean he'd be fast enough to react and counter him. Izuna was shown to be blitzed by Tobirama despite the fact that he had the MS, I know that Sasuke has the dual rinnegan and sharingan, but the whole bending space thing of Gai is kinda hard to get over.

With the Evening elephant, Gai was able to created a massive crater and was even able to use the force of the impact to launch Madara into his own TSB sphere and destroy it, so he most likely could break through a PS.

In the end, Gai dies after opening the 8 gates, so he was never gonna come out alive, but I do think Gai would win, because of his abilities and because Sasuke would underestimate him, knowing his attitude, and then be shocked at how powerful Gai is just before Sasuke himself dies.
