2020s Flash, I think. He's probably but a time remnant now, if not completely removed from existence, since I imagine post-Flashpoint Barry will end up as the one to warn 2014 Barry not to mess it up instead of the 2020s Flash.

I also think that Thawne's Speed Force connection is dependent on other speedsters generating it, which is why he was faster when 2020s Flash was faster, and then had to make sure the new Barry grows up to be the Flash. Though, logically, it should have made time travel to any speedster-less point in timeline impossible... So I dunno.
