I like the Harbingers, I personally have a pair of the Harbingers that have the built in wrist rap which I feel are quite comfortable and overall a good glove.
I've never used training gloves ever. I just don't think you can develop a really good grip by using gloves. If you don't want calluses on your hands though use gloves.
I used glove when I started lifting. But after awhile I found that my hands sweat to much in the gloves and gave me blisters. So I lost the gloves now my hands are made of iron.
