No real spoilers. Pretty cool and insightful for someone who's only played a bit of Xenogears (disc 1) and some of Xenosaga 1.
Xenoblade Chronicles always looked interesting to me but I didn't have a Wii. The later entries in the series from the looks of it lean heavy into the Shonen look with weeb fanservice.
I've played both. Xenogears is a personal favourite of mine, though Xenoblade is years ahead of it in terms of gameplay/presentation. Not to mention it actually being finished!
XB:C doesn't go into nearly as much religious mysticism as XG did, though. So there are fewer vague terms thrown around near the game's beginning. That was kind of a disappointment for me, despite XB:C including some theological elements late in the game.
Yeah you can tell the team behind Gears was pretty heavily influenced by Evangelion.
