Fushigi Yuugi is the better of the two.  I didn't 
like Tenchi at all.  The only redeeming quality 
of it was Washu.

Fushigi Yuugi is full of drama, action, 
adventure, romance, and intrique.  It's a 
wonderful series that both male and females 
love.  I know cause I've gotten two male friends 
into it.

Give Fushigi Yuugi a try.  You won't be sorry!
