A true longwire is multiple wavelengths long and can be matched without a tuner. Typical impedance will be in the ballpark of 450 ohms.
An end fed wire needs a superior ground comprised of ground rods and radials. The matching device can be a wideband 9:1 unun or a tuner and is often a trouble spot... The typical unun used is an autotransformer type with three windings on a toroid. They work well at the lower frequencies but start to go deaf above 5 MHz or so. Been there, done that. A 130' wire with a 9:1 unun makes an outstanding AM BCB or 160 Meter RX antenna but for general SWL use you'd be much better off with a 66' doublet.
As for a TX antenna I've never had good luck with an end fed wire and that might be because I never put a serious ground system under one.
If you can manage an autotuner at the feedpoint of a longwire you should have better RX results on the higher bands than I did. But, for TX? The efficiency of the antenna will be in direct proportion to the quality of the ground system under it. End fed wires involve much more shovel work than you'd suspect at first glance and IMHO there are easier ways to get a signal in the air...........
