Takes the same amount of time. I am a big fan of using something other than priming sugar but it depends on the beer that I am brewing. It leaves a hint of the sugar in the aroma and the taste. I noticed the biggest difference by using Molasses. It seems to have a thicker head and a molasses flavor. You really have to watch it with Molasses as it can produce a very overpowering flavor.
The amount of each bottling sugar depends on the fermentability of the sugar. Honey is about 80% fermentable versus the corn sugar at 100%. This requires that you use more honey, 4.7oz versus the 4 oz for a 5 gallon batch. If you check out John Palmer's How to Brew, it has a table for the different bottling sugars and the amount needed for your batch size. If you split up your batch you need to calculate the percentage of sugar accordingly.
I want to see how brown sugar and maple syrup turn out. I made an Newcastle Brown Ale which I thought to use Brown sugar but didn't go to the store to get it.
I could see honey being the best pairing for the 90 Minute clone but that is really my personal preference. If you want the hops flavor to stand on its own then just use the corn sugar.
