256 Colours, Chunky Vs Planar, what was better?

I know the Amiga used Planar graphics, but for 256 colours, would chunky be the best format?

Planar, 40 bytes * 200 lines * 8 bitplanes = 64,000 bytes
Chunky, 1 bytes (from 00 - 256) * 320 pixels a line * 200 lines = 64,000 bytes.

It just seems like a lot of effort on a planar system having to go through every one of those 8 bitmaps to set the bit for a colour change? Trying to shift some sprites across seems like it would be a nightmare on a planar system. Is there any advantage of a 256 colour planar system?

Thanks
