1) The RX does not perform the analysis, you'll need to do that in rekordbox on your computer. You CAN edit the grids and make adjustments.
2) There's a lot of differences between the units, some plusses, some minuses. For example, there's 4 hot cues on the RX and only 3 on the CDJs. The jog on the CDJ is larger, has tension adjust, the RX does not. I can't make a full suggestion as every DJ uses them differently and expects different things. What I would suggest is that you read the manual and watch videos in order to familiarize yourself with the unit and its operations.
