I've tried both Maximus arcade and MALA, and only dabbled in Hyperspin. Maximus is probably the easiest to set up IMHO, but the feel can be kind of bland and it's more awkward to skin. MALA is super easy to skin, but isn't very flashy and not quite as fool-proof as Maximis. Hyperspin looks simply amazing and has the 'ooh ahh' factor, but does has a steeper learning curve, and is definitely more resource-intensive than Maximus and MALA. Personally if Maximus could be worked on again by the community and be improved, updated, and brought up to speed with the other FE's then I would take a look at it again.
