Mikrotik is great and has lots of updates and support, plus a great forum where you can get the help you need (community), but it is also a "advanced" product and not for everyone.
I would say, one drawback is you need to know what you are doing when setting it up, it is more difficult than other products, but then again you have lots more options and can do a lot more advanced things than with more regular products.
It all depends on your need and what you are trying to do. I had problems in the start, but as with everything, most firewalls or routers work in the same way, it just takes time to get used to the "thinking" within the product, how they do things, how you use a GUI or terminal windows. This is more tedious with Mikrotik than say other products, but then again, cisco is not much better either, and way more expensive.
I have tried a ubiquiti link Powerbeam PBE-5AC-300 and it was so easy to set up, it was like using a Dlink home device, it does work great and has a, good enough connection speed. But anyone can set that up without any problems. A similar mikrotik device would be capable of so much more, but the more complex products you have the more work you need to put into it.
Mikrotik is much more like a real firewall where you have control of everything, even if you do not need all the options (I sure do not) but they are there. That is nice, as long as you know what you are doing
And if you need a stable product, more so than latest and greatest hardware, do not use BETA, and use hardware that has been tried and tested, simple as that.
