Personally I have a simple matrix for routing and switching, if the customer can afford it I use Juniper, if they can afford it and really want Cisco then I will use Cisco. If the customer wants to put something in that will "just work" for years to come I use Juniper. If they want the cheapest routing solution that will do the job I will use MikroTik. If I was building a service provider that was not huge out of my own money then I would use Juniper switches and MikroTik routing/BNG. I have actually found MikroTik to be very stable and scalable over the years and I have had great support from them. In the early years (10 years ago) I saw some BGP instability under load, but not for several years. MikroTik's also make a great CPE device (Ethernet only). I have not used MikroTik switches so can't comment on them.

Although most Mikrotik products are 100% software-based, their flagship router nowadays, CCR, also has similar hardware acceleration from Tilera.
