I have had 3 off Roku 3s which have performed very well. Unfortunately we had a lightening strike on the house and one of them got zapped so I am looking to replace it. I need to have a lan connection so I have settled on a Roku ultra. Rokus are difficult to get here (South Africa) but I have found an online supplier who have both the 4660R (2107) and the 4670R (2019) in stock. The 4660 is considerably cheaper so I am leaning towards that one but I would like some opinions on whether I would be better to go for the 4670. I don't need anything fancy, don't have a need for 4K and as I say the Roku 3s that I have had have worked very well for my needs. Any advice gratefully received.
The only difference I can find between the 4660/61 and 4670 is the 4670 has 2 GB of memory, while the 4660 series has 1 GB. Beyond that, they are electronically identical. My original Ultra 4640 also only has 1 MB of memory, and I've never encountered any use that I felt the amount of memory was a problem.
Since you require an Ethernet connection, the Ultra is your only option. But based on the rest of your usage description, I don't think you'd ever have a problem with the 4660. The 4660 and 4670 both have an Ethernet jack, as well as a USB connector if you want to plug a media drive in. They both come with the WiFi Direct remote with voice control. I have a 4670 as well, but I don't really notice any difference between it and my 4640.
