I suppose the main question is what are you planning on using them for? Broadly speaking, they tend to get used as small bare-bones squads with maybe 1 demolition charge as scouts for the missions that require such units to avoid losing command points on the first turn.
I personally like the full unit with 2 quads as it feels relatively durable compared to most of our options. They either get Incinerators on the quads and get used for objective clearing or I give them 3-4 demolition charges and stubbers on the quads (in this case, the quads are ablative wounds for the bomb-carriers). Jackals can get good use out of Reckless Demolitions to get 2 uses of the demolition charges a turn and, since they get expose by proximity, they will typically be wounding on a 2+ against most things.
I've never seen the power weapons used and I don't have any currently modeled with them. They theoretically are better than they used to be, but the cost feels prohibitive (same issue for the Mining Laser Quads - looks appealing but points are really tight for the army right now).

Is a Jackal Alphus worth it either with them or on her own?
Thank you.
As of this writing I've been struggling to get her to work under the new book. Jackels running anything but Mining Lasers don't really need her assistance (sadly) given they can get the same benefits by proximity and their general job of harassing objectives encourages them to get close anyway. She is a fairly reliable source of Crossfire tokens with her sniper rifle, but a Sanctus can do similar work with no risk of missing and better defensive abilities.
I feel like she would be far more powerful if one (or more) of the vehicles was given Core access. In the previous book her main strength was improving the accuracy of vehicle units, improving the damage of them now would also be welcome.
