Self-hosting is what I always recommend, especially when it involves customer data. Personally, I use, and recommend Full Help[1]. The developer is super responsive, takes to criticism very well, and engage in meaningful conversations when you have a feature request. Took him less than a month to have PGP encryption support added, from conversation to production. That being said, Full Help is relatively new, so if you want something more mature, that has more features already built-in, and also offers a SaaS version, Cerb[2] is a great option. I used it when working at a big hosting company, and loved it, but the interface is kinda ugly. Honestly, Cerb beat Full Help with both hands tied behind their back, but their licensing model was a bit too expensive for my budget, hence Full Help.
