I ran (self-hosted) TeamCity at a division of Disney for years with hundreds of projects across teams with lots of complex dependencies. To this day (though I haven't kept up as much in recent years), it's far and away the most powerful CI system I've ever used. Rock solid stability, to boot. And it's only become better and better over the years.
Does that mean it's right for every job? Not at all. Sometimes you just need simple and accessible. Things like CircleCI or Travis or Heroku's CI. But not Jenkins. I put Jenkins into the same category as TeamCity, and it falls far short.
If you've outgrown some of the other options and need really powerful CI, I can't recommend TeamCity enough.
