i can confirm driving class 1 is much better then stupid bus driving, you wont get spat at you generally have more than enough time to reach your delivery point its not as stressful but its anti social as im driving for an agency i only see 2 people every day, the security guard, forklift driver your on your own most the time.
good points since you drive a bus you will naturally drive smooth and brake smooth which will help keep the loads intact, also driving forward is a piece of plss just that bulk end when turning take a bit of getting used too, and reversing is a pain in the arsse anyway if you need any help ask me as i was once a b driver
