If you only have one antenna I would go as high as possible if you have
good coax. Perhaps tempering the height a bit to keep it away from from
big HF antennas to some degree.
In the summertime Es is the the main prop mode. IMO the angle of long
haul DX on Es is more or less the angle of the first hop. There was an
amazing opening to EU on June 29th from the western US (especially NW
US). My old array with an average height of 63 feet was best most of the
time. But I had a little run of F stations that were stronger on a
single yagi at 44 feet. So especially on Es higher isn't always better.
However IMO on the vast majority of DX the angle is below 7 degrees,
probably several degrees below, which is where my old array rolled off
gain wise. But every once in a while the angle can go way up. I have a
friend in MT that has an 11 degrees horizon toward EU. He had never even
heard EU much less work it on Es until the June 29th opening. But I
think angle that high is somewhat of an anomaly.
F2 and TEP are lower angle generally. But this poor sunspot cycle hasn't
been kind to 6m in the US. However if you are in say Florida you will
have TEP to S.A. much more often (as you know).

If you get interested at all in 6m the obvious solution, and desire,
will be to have a high and low antenna. With the high antenna being as
high as possible considering coax, etc and the lower around maybe 35-40
feet. 55 feet over flat ground is a pretty good one size fits all the
angles height. But lacks a bit on the low angle.
WARNING: 6m is addictive
