If you're going Mumbai within budget with speed so that will be the good option for you but if you're travelling in CC of this train so that will be a tough challenge for you. I seriously not allowed those person to board this train who are not familiar with roadways bus seats. Yuva and Garib Rath CC seats are just like the same. OIf you're doing short journey so it will be fine otherwise dont choose until your last option. I personally booked seats in CC in this train and didn't sleep whole night but getting confirmed seats instead of standing in other trains general compartment so it is the better option.
