I have no idea what the basis is for asserting that Awlgrip is materially harder to patch or blend than Awlcraft nor that Awlgrip repairs don't hold up, but to your question, I've found the colors don't always match up very well between the two. To patch Awlgrip, Dremel the problem area, patch with 3M vinyl ester fairing compound or epoxy mixed with fairing micro bubbles, sand flat-flat-flat, use an airbrush to apply the primers and top coat WITHOUT masking tape, wet sand with 800 grit to knock off the buildup around the edges, then 1500, then 2000, then buff. With colors, you'll never get quite the right color due to oxidation of the surrounding area. With grays or whites you can't see the repair unless you really, really want to. If I have a 1" square area to repair the total time investment for a near perfect job is around 15 minutes, with an investment of a bunch more time cleaning the air brush or going to the boat on successive days to apply the next coat of paint. So doing a bunch of them at the same time makes a lot of sense.
