I was rather fond of Fujichrome Astia, so most of my slide images you see here would likely be that.
I do recall having done one roll of Kodachrome, but it was such a hassle to develop it where I lived as it had to be sent off to lab. Whereas, with everything else, I could get it developed within the hour locally. When you are travelling and you can get something developed during lunch to see how your exposures are on the first day of your trip, that's important.
