I know that , but putting that all aside and ignoring the parodox arguments that are ever so abundant when discussing this...what would it be and why. Don't think time.

I go forward in time, get winning lotto numbers, come back and enter!

Or, go back in tiime to 1994 and tell myself to get a haircut and stop listening to heavy metal.

Back in time - easier to reflect on past mistakes and how they could've been avoided than to guess at future ones and how to position yourself to benefit best. Also going forward in time could potentially mean aging more (depending on whether it's a 'fast-forward/rewind' or a 'time-jump' movement, hence meaning less time to live, or conversely more time to live if you go back in time. The knowledge of future events from going back in time is also incredibly valuable - you could make enough money to do whatever you want just by going back a couple of days, for example, and while money may not be everything, it certainly can help!

That said, if talking about a 'time-jump' over a significant period of time (say 50+ years) I'd prefer to go forward in time since it's likely economic conditions would continue their steady upward progress, and coupled with various new technological innovations much more would likely be possible.

Way off topic, but reminded me of this song:
