I had water entering the foundation so I upgraded to 5" wide gutters with 4" down spouts. Went with gutter guards that are perforated aluminum plates after reading tons of reviews, forget the name though. All the leaves, pine needles just lay on top of them so yea, the gutter never clogs up. The water never gets to the gutter. So I clean the leaf guards every month, especially during the spring. My old 4" gutters with wire covers worked much better, just couldn't keep up during a hard downpour. The aluminum plate guards cost was in the middle of the pack if I remember correctly.
