Never tried RebornBuddy, their website/forum looked really messy and I couldn't even find the information about it that I wanted.
Miqobot has it's ups and downs. Biggest thing is that it's overpriced with no other pricing options. The crafting bot for it also takes way too long to "solve" a craft while free alternatives like ACME exist that work instantly and in a very smart way.
The best parts of Miqobot are basically the Gathering, Gold Saucer, and limited combat features. But even with Gathering, expect to do a little work yourself to get your gathering profiles setup, it's all external imports or making them yourself. Other than that bit, though, it's probably the most user-friendly bot. Not difficult to buy it and start using immediately, plus I think they still have a trial.
Miqobot will probably be slightly more worth the price tag when it gets Trusts functioning. Would be a good way to quickly level your jobs to cap in a safe environment. However...Miqobot is pretty slow at adding new features/fixing old features. And their progress is very invisible, months of saying "it's coming" but not a lot of information about how long it'll take.
Whether or not it's worth paying $10/mo is up to you though, there are other bots that are much cheaper. Try a few things and see which works best for you for the price.
