I haven't done much with the others, but I can't imagine there is much difference. Jenkins has a ton of plugins, but the biggest reason I would choose it over the ones you listed is so that you're not locked in to a specific provider. At work quite a few people were using gitlabCI, but recently corporate signed a deal with microsoft to use GitHub. So now everyone using gitlab ci is going to have to recreate their deployment process.
