I agree with the above post for the most part, but also would like to recommend that you check out the club. While most judo clubs do practice throws more than matwork, mine is about 50/50. If I never checked my school, and thought all judo was split that way, I also would have done BJJ. My school is pretty much a perfect 50/50 split and I love both. My advice is to definitely check the schools first. With that said, however, I agree that 99.99% of BJJ schools will focus on more matwork than 99.99% of Judo clubs.
