Marchosias seems the most loyal and useful out of all of them but that’s only after a quick google search.

@JokuSSJ

I would take that offer, but what would happen if you used their magic for both good and some "Self-Serving Deeds"!

Also What powers do these Monsters give you?

Bael is the only archdemon here so I will pick him.

If i correctly read what Vassago does, i have:

.Clairvoyance

.Precognition

.Retrocognition

Choosing me as their master makes sense, but them having something to offer doesn't.

Forneus would be better compare to these guys marchosias is better I suppose compare to other just because when I've read the goetia all of these demon's have a very untrustworthy looks and I feel if I'm being their master the question would be what they can offer not what I desire

Honestly I didn’t Choose either of them, mostly because nobody told me what any of the Powers are!

Most of their powers tend to be the same tbh.
