If you shoot only 4x5 get the 3010 over the 3006 because you can do 10 sheets instead of 6. If you will go to 5x7 at some time the 3006 is nice. Better is to have both. I think the 3000 series expert drums do a much better job compared to the reels in the 2000 series tanks. I have both and it's rare that I use the reels.
