Coming from a 99% online experience, No.
Later in MK9's lifespan, I tried to learn the roster and picked up some shitter characters like Jade and Sheeva to troll and have fun with. Despite their matchups being objectively shit, I've never felt like there were situations where they truly didn't have a way out of a bind. Sure, you might have 1 option and it might be horrible and not work, but you at least feel like you can outsmart your opponent and have a fighting chance. A big part of it is that it's always hype when it works.
With Injustice, I don't feel that way. Some matchups are just unwinnable. It's a problem when Aquaman gets more chip damage from blockstrings than Harley gets from punishes. It's a problem when you have to respect 4 specials from Zod full screen lol. It's a problem when Zod's secondary zoning tool is faster than Harley's primary zoning tool. It's a problem when 16 Bit goes into Grand Finals against Theo and declares on stream in a pre-game interview that he sincerely believes he has no chance of winning.
There's also the issue of execution vs. brokenness. Call Kabal's dash cancels or Cyrax's resets or Kenshi's zoning or Sonya's rushdown broken all you want, but they all took a significant amount of execution skill and practice. Only good Kenshi players like Pig could consistently keep players out and time spirit charge correctly. Fraud Kenshis get zoned out and cross up punished free. Contrast that with Injustice, where Martian online can get overhead tele into mbb3 into b12 into push absolutely free and some characters just have to completely respect it. That shit takes no effort at all. Aquaman requires no skill either.
Last, but certainly not least, I was raised playing the MK series, not reading comic books. The nostalgia factor for DC just isn't there for me, so I don't feel attached to it at all.
