If you're looking for Prog/Power Metal, lead with the first four - especially Forgotten Suns. This one is just an EP, but their most recent release is killer (as are their other 3 releases). The Sorcerer one was pretty decent - aided by the fact it's fronted by Anders Endberg (of Speaking to Stones). Mind Odyssey gave me a Pretty Maids / Accept vibe.
As for the others... not quite neo prog. Inner Odyssey is all prog - listing bands from PT, to DT, to Flower Kings, to Circus Maximus as their influences. Killer album
Klone - kinda in the same vein... have more of that grungy/wall-of-sound effect, like Devin Townsend
Arcane Atlas - classic Prog sound. More keyboard led ... think Rush + ELP. So, I guess that's neo-prog.
Lake of Mind was the weakest of the bunch - more straight forward metal. Still pretty good though.
That ought to help you prioritize. Happy listening boys.
