A few things.
It ships the two most popular characters with each other, a common thing in any fandom.
Second, Twilight do have really good exchanges, and their episodes together are really fun, so I can u understand it. Third, it's nearly a classic/cliche, 'Nerd and Jock fall for each other', so as a Rarijack shipper, I can totally see the appeal since Rarijack is cliche, 'city and country'.
Of course, Rainbow isn't a Jock, and Rarity isn't a city girl, but the similarities are there.
One more thing. Twidash is high tier, but it currently isn't bigger than Rarijack, and that isn't as big as sparity. One nice thing to note is that Sparity has always been leagues ahead, usually over a thousand images bigger than Rarijack. Now it's only 700.
Now, while I much prefer Sunsetsparkle to Twidash, both are very good :)
