The view is better low down. No point going higher except for two reasons:
Smoother air above the clouds rather than below
Better visibility above
Better TAS especially turbocharged
Better Radio and Nav
Less collision chance
Different scenery equally as beautiful especially some cloudscapes
Better weather avoidance even with CBs
Maybe above the icing levels or less likely to be flying in visible moisture
Etc
Faster speed, less fuel,more endurance
Better gliding range
CAS potential for IFR pilots
More favourable winds in direction or strength ( can work the other way around to less favourable )
All the above not guaranteed but more likely
Pace
