Limbo is better IMO. Kamui is very overrated. Kilt two fodders and gets wanked like no tomorrow.
The title says it all ^^
It's called reasoning. If Obito had both Kamui in his eyes, the only people that could really stand against him would be S/T users and Rikudous. The fastest man in the world couldn't hit him. The power to be virtually untouchable and to create a Kamui-snipe from a distance is dangerous.
And if Sasuke got both sharinnegan in both eye's he'd solo Kaguya neg dif. <- See what I did there? I sound like a fanboy. Double Kamui Obito goes blind in 3 fights no more than 2 kamui a fight GG. Limbo>>Kamui
Except not just anyone has access to speed on the same level of 6th Gate Lee or the strength of Gai. Kamui isn't exactly just something you can run from because it works like a black hole of sorts. Even if you feel the build-up of pressure in your eyes, it doesn't mean you can dodge. Remember what happened with Lee vs Sasuke, Sasuke could track and predict Lee's moves, but his body didn't have the ability to dodge. Not many people have the speed to run away from the range of the barrier that forms and once the barrier forms, it pulls you. If you try to run, it's just gonna drag you in. The only way to escape Kamui once you're caught is Space-Time, and it's extremely difficult not to get caught, only a few people can avoid it.Lets see, it took double Kamui speed to outpace a GoudamaYou must be registered for see links. The same Goudama that had been outpaced by a 6th Gated LeeYou must be registered for see links. Which means to outpace a long range Double Kamui it takes 6 Gated Lee speed. And dodge a single long range Kamui it takes half that speed. That's not hard to do for most Kage level characters. Furthermore, another counter can be too block Kamui's field of vision with a Jutsu, which is easy enough. Sensors would be able to sense the pressure building up inside the eyes (Like Ametarasu) before the technique is even used, and act accordingly (Even the likes of Suigetsu have displayed some level of sensor ability), others can simply run at all times or simply use a Jutsu once they see the barrier appearing. Clones are a neat counter to Kamui as well.
If we are talking close range, it is very easy to avoid Obito touching you. Someone of Base Gai's level of strength should be capable of avoiding the touch.
As for Limbo, the only way you can even see Limbo is Via Rinnegan. And the only way you can hurt a Limbo Clone is with the chakra of the Sage Of Six Paths.
As you can see, the amount of counters too Kamui is pretty decent. Meanwhile the counters to Limbo are narrowed down too one.

Edit: Actually, that scene with the Onmyoudon and Pein's missile show that Kamui can "latch" itself to you. Even though the sphere and missile moved from the spot that the Kamui was initially activated, the Kamui barrier followed. The missile was warping as it was moving, so simply trying to move out of the way won't work.
6th Gated Lee is pretty damn fast il give you that. But their are at least 10 characters faster the him. And that's too dodge a long range double Kamui. By strength of base Gai, I mean being just as powerful as base Gai, not physically, but in general. Base Gai would be in the High-Jonin to Low-Kage Tier. As for sensors, they can dodge Kamui last second, kinda like how Naruto dodged the 3rd Raikages spear. So just before the barrier forms they move out of the way. Of course not many characters can do that either. Then there is the Jutsu varient, by simply using a Jutsu to block the field of vision, Kamui will end up sucking up the Jutsu instead of the initial target, of course not many characters can perform seals fast enough too pull this off. Out of those 3 ways to counter Kamui, there are probably around 15 characters that can actually do it. In other words, there are about 15 characters that can counter a Double Long Range Kamui. Meanwhile, the amount of characters that can counter Limbo is 4 (Kaguya, Naruto, Sasuke and Juubito), basically, only the God-Tiers.
Also, Clones are a perfect Counter to Kamui
Only if Kakashi follows his target with his eyes.
1. Kaguya
2. Madara
3. Naruto
4. Sasuke
5. Obito (Jubi Jinchuriki)
6. Ei
7. Lee (6th Gate)
8. Gai (Probably like 2nd-3rd Gate)
9. Mū
10. 2nd Mizukage
11. Itachi
12. Ōnoki
13. Danzo
14. Orochimaru
15. Bee
16. Kisame
17. Kakuzu
18. Deidara
19. Sasori
20. Nagato (Healthy)
I don't want to name more, but that's just 20 Characters who have the ability to counter Kamui. Its not as OP as people make it out to be.
Bolded are the only people who can get around a double Kamui-wielder.
Limbo is better IMO. Kamui is very overrated. Kilt two fodders and gets wanked like no tomorrow.
