I'm a fan of almost all the above. A (maintained) grinder with a 135 degree sharpening jig will save you a lot of money and down time. Just something to keep in mind when you're on CL or any tool BST.
The coated bits don't hold up as well after the coating is gone but most under-estimate what can be done with a single HSS bit especially when you get your feeds and speeds figured out for the material. Back off the pressure a little and let the tool do the work is one of the things that I have to remind myself often.
Coated seems to be the overall bang for your buck if you don't plan to sharpen them.
Carbides tend to chip and are harder to upkeep. Most are carbide "tipped". HSS is easy to maintain but has a lower heat tolerance and will anneal.
