Rofl, I was about to say team 1 till restrictions.
Team 2 low diff. How?
Simple. Without [restrictions] Team 1 has nothing to get past susano'o or YM. For that matter, Team 1 can't even counter sasuke's Enton sword. Sasuke's mastery is so great that he can either make a susano'o enton sword to blaze the entire area, or he can use his orb to light up team 1 like candles. We don't know how obito escaped amaterasu, and for all we know (since it hit his zetsu arm) he used mokuton to 'drop off' the affected area. Removed that zetsu part. Used izanagi. Or used kamui(unlikely, as the flames would warp with him as seen with konan's tags). Therefore, kamui alone is extremely unlikely to be the counter for amaterasu. With that alone, an EMS sasuke easily has a massive advantage in this fight.
Going further, excluding sharingan, itachi is easily the most intelligent and skilled ninja in this line up. With him to guide sasuke, and protect sasuke (as with kabuto) The chances of team 1 winning - with the current restrictions - is laughable at best.
Itachi can effortlessly handle kakashi in this matchup since their arsenals are somewhat equivalent. The fact that kakashi has MS doesn't shield him from itachi's genjutsu (as seen when his clone got trapped by a 30% itachi clone), nor would the idea of not looking into itachi's eyes favor him well. Though kakashi likes to use shadow clones, itachi also loves to use it too. The fact is, itachi has always shown a capability to push kakashi to the edge, and with sasuke as backup kakashi would easily be defeated. Because this isn't a large battle where kakashi can use team mates to hide, he won't be getting the necessary time to effectively start up kamui on his randomly moving enemy target, nor would he get the chance to analyse whether he's aiming at a shadow clone or not. Kakashi's MS would be reduced to defending against enton arrows (which sasuke can spam the shit out of due to his almost negligible restrictions with EMS) while itachi uses his incredible speed and skills to pressure team 1.
Inside a susano'o Sasuke would be safe from any attempts by obito to kamui him, and itachi's skill would make it less likely for obito to get the chance to successfully sneak up on him and land a successful kamui snipe. Itachi would also put his shuriken jutsu to good use to counter simple attempts by team 1 etc.
TL;DR; Team 2.
