I like First Contact the best.
Haven't seen Beyond yet, probably wednesday. Seems decent. Thought the first reboot film was pretty cool, though I didn't like that they went for the cheap alternate timeline approach. Still, one of the better Star Treks to me. Into Darkness was okay, I liked Cumberbatch, but a step down overall though and below say Wrath of Khan or The Search for Spock for me. I'd say The Voyage Home and Generations come after that. I actually enjoyed Nemesis, ignoring the issues in Data's story, as well, but found the very first movie incredibly boring.
The first reboot Star Trek was retroactively dubbed "The Future Begins", by the way if you want to be thorough...
