I think they're worth them. They're good quality knives for the price & that's important. They'll do what you need them to do & not break the bank or upset you when they get scratched up.
As for D2 or 1095? That's up to you. Typically, 1095's easier to sharpen & great out in the field with very little. D2 will hold an edge longer, but are more difficult (harder) to sharpen & "probably" won't be as easy to sharpen out in the field. From what I've heard, 1095's better for chopping (I believe less chance of edge chipping, etc) & D2's better for cutting.
You really can't go wrong with either, but if you're into hardcore bushcraft & are out in the rough for long periods of time, I'd probably go with 1095.
Hope that helps.
