Yeah, good idea. Xenoglossia kinda screwed up the characters like Yayoi wasn't as enthusiastic as the main series, Yayoi and Iori kept fighting as cats and dogs Those two are best friends usually right? , Makoto kinda became a bully, Yukiho wasn't as shy, etc. And I got that from just from watching a bit of the first episode and a few funny scenes on youtube. Though the opening themes are catching, you shouldn't even bother watching X.
Edit: Well, you could still try X, but only if you're bored and finished the main series.
