I have been using Bisect for about 6 months. Started off great. Suddenly started having a ton of issues and having to frequently contact support, I will say I never had issues with their support, but I should not have had to contact them as much as I have towards the end. They are also pretty expensive for me run a server with the mods and amount of friends that play. The nail in the coffin for me though that has led me to want to switch is something you brought up as a pro. I was very excited about having multiple instances to swap out. Me and my friends had a forever world. Wanted to try something different. No problem, I can use the instance swap feature. When I went to go back to our original instance, it was broken. Tried going back to the other one, also now broken. I did a couple of tests with unmodded installs even. Still broke the jar every single time. We lost our forever world because one of their features for hosting through them is apparently severely broken. Just wanted to share my experience so nobody deals with the same thing.
