Interesting comparison on emptyflower. Excerpt:

judo good- lots of judo people out there, LOTS. not much politics. very functional. techniques are tested regularly. ground work is fun. good work out. chokes are good to learn. arm locks are good to learn. pins are great to learn. good for cops. judo guys can do what they say they can.

judo bad- sacrifice throws. jacket dependence- most judo techniques are tougher or don’t work with out a jacket. grip/ hand fighting not taught. striking not taught with entering/ throw set ups- you have to retro learn (but it’s not that hard). no wrist locks. no leg/ knee locks. deadly throws taken out of modern curriculum. slapping- personal preference- i just don’t like it.

Shuai Chiao good- nastier throws taught. very functional. real SC guys can do what they say they can. good work out. small/ bad joint locks are taught (wrist , neck, ugly/ damaging locks). good for cops, great for modern combat (kill/ disable, not arrest). easier to lose the jacket/ techniques not AS jacket dependent. closer community, you know most guys, or their teacher, or reputation. striking flows very easily. rooted in combat still- the link to GM Chang is priceless.

Shuai Chiao bad- not too many SC guys out there (in US)- lots of old politics. lots of CMA guys say they study SC, but they dabble in it, so some instructors can show techniques, but not do them- the dull fancy sword. no ground work. some SC guys are too jacket dependent. get asked stupid questions- “it’s kung fu? where are your silk pajamas? you believe in Chi?” thing sometimes. not too many tournaments.

Would be most interesting to mix and match. There are also a few interesting threads like this one on judoforum about either no-gi randori or whether there should be a no-gi competition format in the same way submission grappling a la Abu Dhabi championships came out of bjj but also other grappling and has really gotten more limelight. That sounds cool to get to the essence of stuff, not the weird specifics of different formats and rules and politics. There is more interest in how these kinds of training relate to the less restricted sport format of mma or self defense scenarios (gi practice probably useful for most climates unless attacked by that topless man – bleagh – someone mentioned). The question and attitude themselves are good ideas. How does x apply to x itself, mma or self-defense and what has the most bang for buck across areas? A practical line of inquiry, not a stick-head-in-sand kind of defensive response, is useful and interesting.
