Which warbond should I buy at the moment?

I am not too sure if this question has been asked a lot already or not, I haven't been playing Helldivers this past month, but I currently have 800 SC, and I would like to ask anyone which warbond is really worth buying.

I wanna buy the first premium warbond because I really wanted the senator, but I heard the other guns/armor there are not that worth it. Then I also want to get the electrical warbond, because I want the sickle and the silly helmet that looks like the Walter Dog meme. and then I ALSO want the newest warbond because I love those explosive weapons, and armor. But I really cant choose which one to pick. I know its still all up to me but I still also want to have a good experience overall, and I havent really tested most of these weapons myself (except the sickle and the fire shotgun, bc ppl were dropping it as they died.).
