If it is just you wanting to get back into the game then there would be no benefit to staying on a legacy server. If you're looking to reconnect with old friends then a legacy server is just fine. Also, you'd probably want to start fresh and level a class up from 1 to 50. Treat it like a whole new game (because it is) and start from the beginning.
FYI the game is now like World of Warcraft, just without all the bells and whistles. If you enjoyed vanilla or Burning Crusade you'll be right at home. Everything is highly instanced. End game is vertical progression (gear treadmill) and not horizontal progression (grinding for years for sidegrades in FFXI). Up to you whether those are good or bad features.
The game is routinely on sale so you should be able to find it for a good price.
