The flexibility of semaphor allows me to manage my builds in an effective way for different platforms from iOS to Android with ease! It's also easy to integrate into my Jenkins pipeline if I need it later down the road. Also really good customer service team that helps out when you get stuck or have questions along the way. There are some things they could improve upon but nothing too major at this time. As long as your not looking for something super specific then definitely try them out! We use semphores primarily because its simple yet powerful enough to build complex applications without having tons of plugins needed which can slow development speed drastically.
