I feel like modern pitchforks are not as great as old ones, having 4 straight spikes isn't efficient in regard of picking hay.
I'd say vintage pitchforks shaped like this :

are more conveniant, and generally last longer due to better materials, I just like to mod mine in order to had an handle, and a grip in the mid-section.
There's also this shape, that I find useless, it's not efficient at all. If it didn't get me laid once in this BDSM bar, I would say it's my worst purchase ever.
