Over priced mma gym , judo same thing for lot cheaper
 

Why train bjj at these commercialized 150 month gyms when I can do something very similar but for a third of price 40 month called judo. Judo does ground work too.
Used go to these over priced mma bjj gyms and found unless you got time to go everyday it just ain't worth it
Talk to friend and does judo and says it's so similar . Bjj just overpriced since it's a big fad

While I have a high appreciation for judo and training with judokas, training at a judo only gym won't meet everyone's goals unless you're strictly in it for judo. BJJ is definitely derived from judo newaza but the sport itself has evolved a lot since then (rubber guard, 50/50, berimbolo, etc). I am only assuming but I feel because BJJ is grappling focused, it can teach you a lot of intricate grappling details which may get passed in judo (where newaza is a part of the sport not the entire focus) Bigger MMA gyms also offer striking and mma specific classes which may be additional training others are looking for. I also respectfully disagree that BJJ is a fad.
