I learned Common Lisp about a year ago, and is teaching my friend CL. I learned 
Elisp a bit later, because I tried to customize my Emacs (which I started to 
use because of SLIME).
I think it’s pretty fair for me to say about beginner experiences.

I would say, it is indeed ugly; but it wasn’t a pain point. That’s not 
something begginers would say it’s complicated or harder to learn.
And, it allows beginners to gripe what ‘macro’ is, because it’s similar enough 
with real code to show that macros generate ‘code’ and different enough with 
real code to show that macros ‘generate’ code.
I immediately understood what macros do by just looking at the backquote, and 
my friend is having a similar experience.
