Best route for scenery along the roads between Istanbul and Izmir, turkey
 

I'm a little unsure on the route I should follow after leaving Istanbul? My options are:

1) taking a bus to Iznik, then Bursa (as I've heard it's a scenic ride, and not so lengthy - Is it really true it's a scenic ride?

2) ferry to Bandirma, and bus connection to Cannakale, or direct bus connection to Cannakale (from Istanbul) - only reason I could think for doing this is getting to Aegean sea - nearby to turkish islands Gökçeada, and bozcaada, but after looking at pictures of these islands online, and the mountain Kazdagi, I'm not TOO impressed with the landscape scenery, and breathing photography near Cannakale (which is what I'm looking for). Also, I am no so interested in history, or archealogy, so I hope that helps you suggect a route connecting Istanbul to Izmir, taking the most beautiful natural, and architectural attractions along the way.

Thanks for helping me...
