Not in my opinion, especially JL1. I'm puffing one right now, and I find it bready, creamy, rich and smoooove.
Frankly, I don't find any CCs that strong though. But I think JL would acceptable for a beginner. Not too complex, which is wasted on a beginner, and still gets to the essence.
Party shorts might be a good one for the list too. Not intimidating, gets to the sweet spot fast, and really captures the Partagas profile without requiring much patience. The D4's are a hell of a good Party rep, and you've got that, but petite coronas are an easy grab for a virgin palate.
