I didn't do a tour for either. I don't think you'd go wrong either way, if that makes you feel any better. That said, I would choose Batllo. More cool stuff to see. For me, 80% of Pedrera was the roof. Batllo was a good hour-plus of cool.
You don't need a tour (not sure if they give tours), but do rent the audioguides. They are well worth it. I basically agree with boyreporter. you can't go wrong either way, but my first choice would be Casa Batllo. The entire interior (all the floors) are amazing & interesting & different. The best thing about La Pedrera is the roof. One floor has a museum, & the other floor is a replica of what the house looked like years ago with furniture, etc.
Gg...I agree with the two posters (It's uncanny, but Kwoo and I almost always agree!!) You can do both buildings, they're very closeby...no tour guide necessary.
