Hi guys, just wondering i wanna enhance my ground game for amatuer mma and wondering which of these two gyms you'd recommend i narrowed it down to looking at these two.

Manchester BJJ academy, steve campbell coach (Carlos gracie jr BB)

or

Gracie Barra manchester (Lucio lagarto rodrigues)

Anyone been to these gyms to give me a heads up on which would benefit me more?
thanks in advance
