Looking on Amazon or Target it's hard to tell what's the latest and greatest. I need one that can handle streaming HBO Max and some of these other channels preferably with an SD card, but I don't need one with the headphone slot.
(Im assuming the SD slot speeds things up?)
Id also like to find one that can increase the speed on youtube. Apparently, some can and some cant.
The SD card is only used to expand the channel app storage, to reduce how often the unit must download a copy of less-used channel software before starting the channel. That's all they do, and they don't otherwise speed up the unit. Only 2 GB of the card are used, no matter how big the card is. More recent models have more installed memory for this purpose and SD card slots have been discontinued.

Also, more recent Roku will allow USB hub to be attached to allow USB memory stick to stream personal videos from the memory stick (as opposed to using screen mirroring from a tablet or laptop). See YouTube videos on how.
Some also allow hardwired Ethernet using a cheap 3rd party dongle (streambar does this), good if your WiFi is not strong. Dongle spec is in a community post.
