Welcome BB, the Tele would be easier to solder up , but really the JR wouldn't be much harder.
There is a heap of help here, go slowly and you should be fine, lots of diagrams that are pretty easy to follow for a novice and plenty of help if you get stuck.
Both these models have been successfully build by first time builders with excellent results, and plenty of build threads you can use as a guide. Follow the recommendations and take your time, it would be hard to fully muck it up.
My advice would be go for the kit that grabs you the most and go from there.
