I wrestled for quite some time and coached it. I don't have any Judo experience, so take what I say about Judo as speculation...
Both should give you an equally good workout, if the intensity of training is equal, ie how much time is spent "on the mat" vs instructional type stuff.
The point of wrestling is to get your opponent on their back and pin them, or to score more points. There's no "finishing them;" only pinning them.
Judo's emphasis is a finishing throw, joint lock, or choke. Yes there are points, but that's not my perceived ultimate goal.
Judo will have a syllabus and a somewhat rigid structure to advancing. Wrestling will have a loose structure to advancing.
*********thanks for your reply! pls see my latest group reply...
its too early for me to know about the structure of the class but even from 1 class it was quite managable (in the actual wrestling instruction parts of the class)
for me i get confused if i do too many things at once. i learn simply but i learn deeply. and in the class we didn't do anymore than 2 moves and loads of practical application. so that was awsome for me and suits my learning style.
Wrestling can be easily adapted to "the streets." Throwing someone onto the pavement is going to hurt, regardless of it's a judo or wrestling throw. It's easy to make wrestling holds/moves painful to an opponent. Judo's holds are designed to be painful, not to get someone onto their back for a pin fall.
Judo and wrestling throws may look different and be named differently, but the principles are the same - it's body mechanics and the feeling of push/pull that makes a throw truly successful, not muscling it.
Wrestling has weight classes. Judo competition does too. If you're training non-competitively, judo classes may have you train with a lot of different weight people. Wrestlers who weigh 100 lbs don't wrestle people who weigh 150 very often.
**********this is a good point... and i hope i never encounter the need to defend myself... but yeah good point to consider...
It depends on what tickles your fancy more. Watch a few sessions of each and decide. I haven't been around too many judoka, but the ones I have been around were just as tough as any wrestler I've been around. There's no hiding in wrestling nor judo. You can throw people or you can't. You can submit/choke people or you can't. You can take people down and pin them or you can't. There's really nothing hypothetical like "I could have knife handed him in the throat, but I'm not allowed to as there is in many striking arts. Disclaimer- I'm a karate guy, so I'm not bashing.
