Hi cadm8,
'Grid survey' with oblique imagery should lead to better results. However, you should also get OK results with your survey design.
Have you checked the image quality? Blurry/low quality images might explain some of your texture problems.
Additionally, have you cleaned up your sparse point cloud using EDIT > GRADUAL SELECTION before computing the dense point cloud? You should get rid of all tie points with high reprojection error and high reconstruction uncertainty. Also use aggressive depth filtering for the dense point cloud.
Last but not least, disable 'duplicate' images which have been taken at the same location. I've experienced some issues in the past when pictures were very very close to each other and basically had the same orientation.
I hope that helps and improves your results #fingerscrossed

actually there was oblique imagery involved both in grid collection, as well as a downward spiral, as you can see in the attachment. I guess though that there should be a better survey grid and more overlap, maybe more than 80%...
