I would. It’s a good game. I like to play the game as the developer intended unless there is something horrible that really needs to be fixed. There are probably some quality of life mods that don’t change the basic game play that may be worth it - people talk about them above, but I don’t think the game needs a re haul to enjoy it. Not everyone thought the Long War 1 changed the game for the better.
Playing with The Long War 2 later kinda makes it seem like a game with a new expansion pack. Then you can decide if it is better for you.
