In the ARRL (2011) section 9.3.1 about LC oscillator circuits it says that "[t]he N-channel JFET source follower shown appears to be the most popular choice nowadays", but does not explain the advantages of JFETs over BJTs.
All I can think of is the fact that BJTs need extra components in order to be biased, and JFETs have a higher input impedance.
What would be the advantage of a JFET (e.g. J113) over a BJT (e.g. MMBTH11) for this application? And why the preference for an emitter follower topology?
EDIT: Here are the schematics from the ARRL (2011)
And my simulation which works well when tested on breadboard
