Very good experience with Việt Tân Phát bus to travel between Sài Gòn and Mang Đen, the seat / bed are really comfortable and suitable for tall guys, it is worth paying a little more (compared to other bus lines) for such a long trip. I will certainly use it again later.

Drivers and drivers are enthusiastic and polite. Check for enough passengers every time you get on and off a stop. Comfortable car (I took the car for 520k/ticket). The stop is relatively clean (I give it 7/10). The bus stops at about 2 stops for the whole trip, so if you urinate a lot, try not to drink a lot of water before departing. The departure time on the app will be different from reality, the morning of the departure day the bus company will call to schedule a time. You must arrive on time for the bus appointment.
