It really depends on where you are. We did the EBTA a couple of years ago and had a port room, honestly it really didn't matter. Some ports one side had a cool view, some ports the other. Honestly, we don't use the portholes that much, we usually go on deck to get a good view. If you're looking at a verandah room, as long as you have an unobstructed view it should be fine.
Cheers!
