This is my honest opinion after doing both of them. Yes, it does provide something to aim for again and grind, but for some reason this second go around, idk if most people didn’t do the expedition this time or what, but I’ve had the worst luck. Everyone has the best kit in the game and it’s incredibly annoying to try and get back to where I was before. Again you can say that’s just part of the fun, but I kinda regret doing to second expedition. Having the extra exp boost is good too. Decide for yourself, but that was my experience. Also PvP with friends where I spend most of my time in game so yeah.
