Olympus seem to have chosen to make their own way with a 4/3rds format which some like some don't.
I am not sure when Leica first invented the 35mm format it was anymore than because it was twice the size of existing cinefilm at the time. Some would argue it matches the golden section rules of composition and therefore has advantages over the 4/3rds system.
Olympus digital slr cameras certainly produce good results and for a reasonable price only disadvantage I see is the lack of 3rd party lenses.
Enough is said about the 2 market leaders for me not to add to it.
Each make and model has advantages and disadvantages it is a case of weighing these against your needs and budget. Just because a camera seemingly has a higher spec. does not mean it produces the best results for your particular needs if you do not require that spec.

Personally I would like a Leica R9 with a digital back and good selection of lenses to suit - but thats just dreaming ....................zzzz................ :))

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
