Given the following post, respond as if you're commenting on Reddit:
human
(Starship Troopers/The Forever War/The Lost Fleet/Star Trek/Star Wars/and others) Differing principles of interstellar travel.

Two questions 

Which fictional travel method is more favorable?
Which fictional travel method is more realistic?

Starship Troopers = Cherenkov Drive days to weeks between A to B no time dilation effect

The Forever War = Collapse Star jumps almost instantaneous travel between massive distance from A to B suffers from time dilation effect 

The Lost Fleet = Jump points and Hypernet Gates, jump points days to over a week between systems, Hypernet Gates days to over a week between massive distances.  Do not suffer from time dilation.

Star Trek = Warp Drive factored differently on how fast you can go there is a whole Wikipedia article on it.  Do not suffer from time dilation.

Star Wars = Hyper Drive factoring again on how fast and far you can go is up for debate.  A parsec is a measure of distance.  Do not suffer from time dilation. 

I apologize in advance, I know this list could be much longer, but I have not read enough. 

There are a multitude of other forms of travel I'm interested in hearing about and discussing.

TL;DR ships go fast no matter what fictional world you live in and no matter what physics say.

You forgot one.

Warhammer 40k = Warp drive, enters a dimension filled with demons made of rape, lemon juice, and torture, to travel from point A to point B. Destination may be off from point B by a few dozen light years. Suffers from variable time dilation ranging from -1000 years to 1000 years.
