Im sure full fat is better but I have ss9 and i dont regret not going full fat.
Dont do any grab work to speak of though so maybe in that scenario, but look at what
@Storrsy does with what hes got
Swopping buckets with hitch open does disable tilt but hardly a huge problem, a bit of deft use picks them up a pop anyhow and dont have the issue loading buckets or attachments as use the gripper on back for all that.
You've had both setups so are better placed to judge but ss9 is a long way from getting out and swopping buckets with gloves and a hammer
