Bag targets are great for field points. They last a long time and can be recovered for even more wear.The are also pretty inexpensive. Cheap ones and more expensive ones work the same, better ones just come with a heavier cover as a rule.
BH targets are a different story. The Cadillac IMO is the Rinehart, they are pricey but last forever in relative terms and both BH and field points are easy to pull out of the material. I have one of the larger ones in the backyard and have been shooting it for several years, the elements don't seem to effect them to any significant degree. Block is also a good target. There are plenty of variations, look at some product reviews to learn more about the most bang for your buck.
