Default Wire antenna - dipole vs inverted vee

I have always been of the opinion that when it comes to wire antennas, the
prevailing rule of thumb is "the higher the better". However, I am about to
deploy a 270' 160m antenna, and -- based on available trees -- I can either
install an inverted vee with a 50 foot apex, along a straight vertical
plane, with ends dropping off to about 15 feet high; or a dipole at 50 feet,
with the antenna in a straight horizontal plane (center and ends at 50
feet), but the vertical plane in a V beam configuration of about 90
degrees.

I enjoy chasing DX - so which configuration should I choose? Would the
slight vertical component of the inverted vee offer me a better take-off
angle than the horizontal dipole? Or should I opt for the "higher the
better" route?

Thanks in advance for your responses,

The effective height of an inverted vee is approximately 80% of its
apex height - depending upon the angle.

However at 50 foot height above ground ether configuration (the dipole
or inverted vee) will be a NVIS antenna system on 160 meters. If you
are seeking low takeoff angles for DX you would be better off using an
L.

Larry,
At 50 feet, the differences between the two antennas
are going to be negligible. Put up whichever will be
easiest for you.
