I think most brewers would do cans if they could. And those that don't would be on grounds of marketing and dogma. It's superior in most every aspect, except public opinion. There's a strong stigma there from decades of cheap swill because cans are more economical and ideal for mass production. The reasons brewers traditionally go with bottles is a canning line is expensive, complicated, and takes up a lot of valuable space. Space that could be better used for beer brewing. At the minimum a manual commercial bottling station could basically fit in a phone booth. Until just a few years ago craft beer in cans was unheard of, but now they're making that investment. But... in the end, all that matters is what the drinker's experience, so whatever floats your boat.
