Necropolis or Castle (Which one is stronger?)

On SoD, and especially if the map is big, Necro will be much stronger. True, Castle also has advantages — it's more mobile (thanks to the Stables and not being stuck gathering skeletons), so there's a chance that a good player playing this town will eat up much more of the good stuff and come to Necro early (on the 2nd or 3rd week) with high stats, magic, and troops picked up from conservatories and hives. Also, Castle has a green respawn, which is much richer than Necro's (especially if he spawned in the Dungeon). And then there's the upgrade of Angels from conservatories to Archangels. But overall, of course, if Necro isn't cut down by restrictions, they are much stronger than Castle.
