Probably both, and more in your urban apartment. I share your misery.
The fact that the ATU could find a match doesn’t overcome the fact that an
antenna showing a 25:1 SWR isn’t going to work very well. The ATU’s match
simply transfers the problem to the feedline and away from the rig. I would
suggest – among other things – investing in an antenna analyzer and doing what
you can to bring the antenna into better compliance. I also have a KX3 and a
Buddipole. The factory-suggested settings for the Buddipole are next to
useless given proximity effects and the fact that the bandwidth of the antenna
is exceedingly narrow. Without an analyzer you can’t really adjust it to the
operating frequency. Except that at 25:1, it probably isn’t close.

Okay I am reaching our to the Elecraft enthusiasts here for some feedback
if anyone cares to chime in.
I am just getting back on the air after years away from the hobby, so I am
not that familiar with band conditions in general. It looks like the
sunspot cycle is heading for the cellar (if it isn't already there).
Recently bought a KX3 and a Buddistick vertical (like, 2 weeks ago). Love
the KX3 it is a great radio... however... so far my efforts to hear much of
anything, much less make a contact with someone, has been frustrating to
say the least. I live in an apartment and am surrounded by power lines for
one thing. The background noise level on 40 is pretty bad varies but is
s7-9 mostly. I took my setup to a nearby park and the bands were
definitely quieter. So the local manmade noise level is an issue (and one
reason I chose the KX3 was the hope that its rcvr and filtering could help
with that.)
Have yet to make a single contact, so I am just wondering if I just
happened to choose a really lousy period of solar conditions for HF? Or is
the base loaded vertical a joke?
I would love to be able to find another ham even close by just to try and
get some sort of an HF QSO even if it is with someone down the block.
...I can tune down to the AM broadcast band and was able to hear some local
AM stations. :)

(On a side note the tuner in the KX3 is great!. That thing was able to get
a match for 80 meters on the Buddistick which was showing something like
25:1 swr. The KX3 tuner clicked and rattled for a while and found a match
to <2:1. Not sure how much actual RF is going out, probably not much... but
I was amazed it could tune to that high an SWR.)
