I really like the looks of the 2600, it seems a great balance of heat, cost and performance. Most of the issues with Ryzen seem to be worked out, however there are still some threads every now and then about how well the Ryzen's throttle under light load, which can impact power/heat. That said, I'd think the delta is minor. This is my understanding of the trade-offs:
Intel:
Better idol power consumption
Processors with iGPU can hardware encode with Plex
More stable on the whole (Though becoming less an issue over time)
AMD:
ECC Ram
More PCIe lanes (This is big for VMing with passthrough)
Cheaper
For myself, I'm trying to get my new Intel E-2176G in so I can do my upgrade, but I view this upgrade as likely a short-duration system with my eyes on the Ryzen/TR 7nm products late next year or even the refresh of them in 2020. The lack of iGPU is really the only down side to me, the power consumption delta isn't that large anymore and will likely tilt to favor AMD with the 7nm chips...
