Its entirely dependant on the way things are ran, what facilities are being hosted, the condition of the field you're playing on and the equipment (barring gats etc)
Thats from being on a team, from a training perspective. Leagues vary in price on many of the factors above but obv, it is different in some areas to others.
With playing for a team you may have to take on board sponsorship payments, monthly fees, etc, which a well organised team will inform you about when you join, like membership fees etc
