Honestly the Baraka matchup is 5-5 with no .5s and possibly 5.5-4.5 in her favor with them. Her zoning can cause him a bit of trouble but with EX blade charge he can punish a low fireball(iaFs might be safe, I personally wait for the low fireball because of its horrible recovery). Once he gets is close he really doesnt have an advantage, but neither does she. His 6 frame d3 can stop some of the levi cancels, although those are a pain for him as well. But when he gets in his d4 range he can keep her at bay because of her poor range on pokes. Blade charge makes Sindel unable to back away from him and iAF or other ways to try and get out of pressure. He completely beats her in the corner game, Sindel has no reset and most of her most damaging combos come from launchers that can easily be blocked. He can bait her wakeups pretty easily and if she decides to stand up in block can F2 into slices for more pressure. His sweep is a good tool in this matchup, because if he knocks her down he can either bait the wakeup or go into F2 slices. If she blocks it he has a +11 frame advantage and can cancel into slices for more meter.
So really to break it down:
Corner game: Baraka advantage
His only true advantage in the matchup. He has his reset which makes it hard for Sindel to get out, has a 6 frame F44 to keep her from jumping out, with meter has the 50/50 with F2 EX slices or b31 b31 b31 F4. Sindel honestly doesnt seem to have a great corner game, but even if she does she can't reset the opponent like he can
Fullscreen: Sindel Advantage
Her zoning is where the 5.5 comes in imo. He is usually forced to walk forward and try to corner her. With EX blade charge you can only really safely punish a low fireball, although a mistimed iAF will be punished.
Midscreen: Even
He can only really use his D4, sweep, and blade charge. His D4 can keep her out of range because of her shorter range on pokes, he can punish any attempt to back away with a dash of his own or if she tries to fireball he can blade charge her out of the air. She has good footsie tools with F12 and 4,4 as well, so she makes it even here.
Upclose: Even
This is completely even. Her levi cancels can really pressure him and make him struggle. However his slices pressure can also make her struggle because it leaves him neutral on block and then it becomes a poke war. He also can cancel any string into slices, and she can cancel most of her strings with a levi cancel, but obviously those have different advantages/disadvantages. Baraka and Sindel both have frametraps I believe, Baraka with 2,2 1+2 F4 and Sindel with F12 b1.
Meter Building: Even
It is even because it depends on where they are on the screen. At fullscreen Sindel has a huge meter building advantage with her zoning. Up close Baraka has a huge meter building advantage because any string canceled into slices is 50% of one bar. 75% if he uses 2,2 1+2 slices
Meter Usage: Baraka advantage
As far as whose meter can be used more to their advantage, it would have to be Baraka. He can use meter for EX blade charge to get in. While Sindel can maybe use it for EX yell for combos, his meter puts him where he wants to be.
Combos: Even
Both of their combos can be ended to put their opponent where they want them to be. Baraka can end his combos in the F4 reset to be at +16 advantage and up close, while Sindel can end her combos in B2,4 hAF to put him at fullscreen.
Footsies: Even
Baraka has great footsies but honestly I think Sindel has really great footsies as well.
So basically she has an advantage at fullscreen, but other than that they pretty much go even in most of their game, save in the corner. As a Baraka player, I can tell you that cornering your opponent is harder than it looks
i agree that she goes 6/4 over kenshi, and i belive her to go 5/5 with jax, csz, reptile, and mileena. i also feel she is 6/4 over stryker. admittedly, though, kung lao is probably her worst match up, and she struggles against kabal as well 
but she is SOOO much better than she's given credit for. very underrated corner game as well as her rushdown!
